i take the train from san francisco to palo alto to get home.
i ride a bike to and from the station so the bike goes on the train with me.  if you are unfamiliar with the bike/train system you park your bike inside the car designated for bikes.  you put a tag on your bike noting which stop you are getting off at.  this way people can stack their bikes accordingly so they dont have to move a shit ton of bikes to get to theirs at their stop.




after i placed my bike in the rack i went to the upper level and found a seat and settled in.  when the train started moving i looked down to see how far buried my bike was.  it was about 4 bikes deep.  this is also when i noticed another bike identical to my cheap cruiser.  it was further in the train car but only 2 bikes deep.  i could tell that this bike was the same exact model but didnt look as beat up as mine and it  probably didnt have a bent rim like the one i never got around to straightening.  anyhow i went back to zoning out for the commute home.




about 5 stops later i look down again to see someone trying to get a bike out from the stack mines in.  by now my bike is only 2 deep so i assume he is going for one past mine.  hes moving quickly so he doesnt miss his stop.  he moves the first bike out of the way and then grabs mine and i assume hes going to move it aside as well.  but then he starts moving toward the exit and i immediately jumped in my seat... but right as i did i remembered the other bike further in the train that was the same model.  in a split second i deduced he must have mixed up the bikes and i decided not to say anything.  i settled back into my seat and watched him exit the train.






now at this point i was fully pumped with adrenalin as if letting this guy mix up bikes was akin to actually stealing from him.  my plan was to wait for my stop, grab the other bike, go home and enjoy my new old bike.   i even played out the scenario if i ran into the other guy again.  since it wasnt my fault he mixed up bikes and if we did indeed meet again we would just switch back.  i was innocent so i tried to  calm myself down until my stop came.






a few more stops pass and i look down again.  my heart skips a beat as i notice the other bike is gone.   maybe someone moved it and i couldnt see it.  i went down to the lower level and looked around.  the bike was gone.  i stood there a bit shocked.  i tried to figure out what had just happened but couldnt really wrap my head around the situation.  the only logical explanation i could come up with was still that the first guy had taken the wrong bike... but if the other bike wasnt his which one was???  





i decided i had continue riding the train to see if there was a leftover bike.  i tried to see which bikes resembled my bike.  one other cruiser was left.  this would have to be the first guys bike.  right?   i rode the train past my stop watching as the pile of bikes disappeared one at a time.  i watched as the other cruiser exited the train.  i continued to ride and watch in horror as all the bikes exited the train.  





by the time i hit san jose i decided to call it quits and go home.  i got off the train, waited for the next train heading north and hopped on.  i walked home from the station and had a beer.  then i got into my car and headed to target to buy another bike.  i still dont really know what happened.  someone accidentally stole my bike and someone else stole someones bike which i was going to steal?
