Nice views of South Mountain, lots of elevation changes and some tricky par 3's make this a very solid muni and probably the toughest in town.  

First my two complaints: the chipping area should have a few more holes with a slightly larger green, and the neighborhood is atrocious.  

Aguila has four features not often found at municipal golf courses:
1) You need to drive the ball well to score well here.  From a lot the tee boxes, the driving area often looks smaller than it is; so, confidence with the big stick is key.  
2) Absence of generous flat lies in the fairway; even if you drive the ball well, you are not always rewarded and are sometimes faced with side-hill lies.  
3) Very tough holes #9 and #18.  Hey, I like to score low as much as the next guy, but the thing about city courses is that they often give you easy closing holes with a good birdie chance; NOT the case here.  Rated 3 and 2 handicaps respectably, #9 and #18 take advantage of the same water hazard (similar to the closing holes at Karsten @ ASU) and put in play some penal, deep fairway bunkers that require precision drives and good approach shots.  #18 plays 470 yds+ from the tips, so if you hit a bomb, you still don't have a wedge in your hand.  
4) Two true risk / reward par 4's - both with water, both greens are drivable from the tee.  #8 is not a guaranteed birdie from the greenside bunkers, but they're a good bailout.  #17 is longer and is a slightly more daunting drive with a more generous bailout option to the right, these are great holes.

A tip: 
Take advantage of the par 5's; all but the last one is reachable in two (at least, that's been my experience).  There are only two par 3's that I would consider good birdie chances (#13 and #16), so if you can roll in a few putts, you're set.

Go past Tent City, drive further south towards South Mountain, and you'll find a nice municipal course in South Phoenix.
