  The coordinates you have are incomplete. They only narrow it down to this general area. And, although it's not a big park, the thing you're looking for is very small. Probably.
  
  Between the train tracks and the softball field there's barely any room for a trail, and the bike rack here is almost lost in the overgrowth. Presumably somebody will come by at some point and prune the bushes, but today you're the only one around.
  
  The trail leads south from here.
  
  You finish locking up your bike and shove the key in your pocket.
  
  [Author's Note: It would be nice to know what you're looking for.]
  
  > About yourself
  Your "hiking gear" is indistinguishable from what you wear to class every day: jacket, T-shirt, whatever. Your shoes and jeans are basically clean.
  
  > look at the paper
  Scrawled in blue ink:
  
  41.664, -91.562
  blue box
  
  During the couple of days that you've been wondering about the origin of these clues, it has been difficult for you to distinguish your well-reasoned guesses from your hopeless delusions.
  
  > examine rack
  The bike rack is a frame of thick metal bars, and your bike is attached to it fairly securely.
  
  > examine the bike
  Yours is not the most reliable bicycle in the world, but it's still more trustworthy than, say, a car. At least when your bike betrays you, it's fairly up-front about it.
  
  > look at the lock
  If you think about it, you could use a bike lock to lock up almost anything. But, now that you think about it, you can't think of anything else you need to lock up.
  
  > X TRAIN TRACKS
  
  The tracks run along the crest of the hill, north to south, from who-knows-where to who-knows-where.
  
  > examine trail
  This stretch of the trail is still cheap asphalt, and there are a few loose chunks and potholes. Other trails in other parks are maintained better.
  
  > Xyzzy
  From far away comes a sound like thunder.
  
  > look at the gps
  You can't see any such thing.
  
  > X SOFTBALL FIELD
  
  Nobody's playing any softball today. It's too wet, or too cold.
  
  > go to the south
  The bike trail turns here, giving as wide a berth as possible to both the softball field and the woods. Cradled in the curve of the asphalt is a pool of rainwater.
  
  On the other side of the trail, a low balance beam and an accompanying informative sign have been pounded into the ground, both encrusted with lichen. Behind them rise the woods to the south, as infinitely dense and expansive as they can manage given the limited space available.
  
  The path leads north and east.
  
  > look at the sign
  The sign describes some exercises for the athletically inclined to try out using the balance beam. You can imagine the Parks Department designing a dozen of these Fitness Stations, erecting this one, and then running out of funding. Or running out of enthusiasm.
  
  Looking around at the back and the base of the sign doesn't yield any clues.
  
  > look at the beam
  It's still kind of damp, but you could probably sit on it. You've sat on it before.
  
  > sit on the beam
  You take a seat and look up into the sky above the softball field.
  
  [...]
  The bursts of lightning would hang in the air for unnatural lengths of time, so that you could make them out in great detail—but when the thunder finally came, it was very quiet.
  
  This was two years ago. Maybe you were talking about something. No, you remember you were sitting in silence, watching the storm pass as if it were a parade.
  
  But then she leaned over so that her head was on your right shoulder, which was unexpected, so you thought What do I do now? and
  then you put your right arm around her. And she said "Thank you," which at the time did not strike you as odd.
  
  Eventually the rain was not falling far away: it was falling on the softball field, and then on the two of you, so you ran off.
  
  [...]
  You stand up.
  
  > think
  What a good idea.
  
  > examine the pool
  Standing water like this pool here is a vector for mosquitos. But it's probably too early for mosquitos anyway.
  
  > jump in the puddle
  I only understood you as far as wanting to jump.
  
  > LOOK INTO POOL
  
  You find nothing of interest.
  
  > get in POOL
  That seems unnecessary.
  
  > TOUCH POOL
  
  The pool of rainwater feels pretty normal.
  
  > Drink water
  That would be a bad idea.
  
  > examine the lichen
  The lichen is growing mostly around the bases of the beam and the sign. It gets by where it can.
  
  > eat the lichen
  (first taking the lichen)
  Even if you could separate the lichen from the beams, you still wouldn't have much of a use for it.
  
  > Go east
  Here is where the curve of the outfield fence gets close to a small rise in the bike path. The incline is such that the asphalt is a little drier here than it is to the east or west.
  
  A lonely drinking fountain stands just off the path.
  
  > look at the fountain
  The drinking fountain seems to be of an older vintage than the other park amenities. Maybe it's from the seventies.
  
  Apparently it's activated by turning the knob on the side.
  
  > examine the knob
  It's made of scuffed stainless steel.
  
  > Drink water
  You take a sip from the fountain. The water is lukewarm, and it tastes like a piece of aluminum foil. Somehow you swallow it down.
  
  The drinking fountain peters out and stops.
  
  > examine the fence
  The fence curves from over there in what you guess is left field to way over there in what would have to be right field. The nearest fence post is missing its cap thing.
  
  > look at the hole
  (the bike trail)
  This stretch of the trail is still cheap asphalt, and there are a few loose chunks and potholes. Other trails in other parks are maintained better.
  
  > look in the circular hole
  It's not a blue box, but it does seem like a good place to hide something.
  
  Unfortunately, there's nothing inside.
  
  > climb the fence
  The softball field strikes you as a lousy place to continue your search.
  
  Although, if you did climb over the fence and head north, what would you find? Past the field there's the mall, and then the Interstate, and the hilly country where you fell off your bike that one time.
  
  And from the ultimate North come the cold winds that bring snow and make life miserable.
  
  > look at the field
  Nobody's playing any softball today. It's too wet, or too cold.
