Buttonwillow has always been one of my favorite tracks..."Bumpywillow" as it's
more affectionately called, is a fairly bumpy, technical, slower track (in normal
direction) in where else, Buttonwillow, CA.  Armpit of the earth, pretty much. 

Going in the middle of July is not recommended.  HOT!  I really do love the track
though.  Button is the only track where they run forward direction one day and
reverse direction the next.  Reverse direction is so much fun.  The "drag strip"
lets you hit speeds in excess of 170MPH.  That's a rush.
