       What an incredible masterpiece of a downhill trail. It has it all. Thanks to all involved in building this and all the new FWS trails!

       The most bike park-esque trail in the shed. So much fun.

       Blue Square flow trail most of the way but ends with a hard, steep black diamond rock garden. Much harder than three saws. Such a fun trail!

       Starts off slow and then blasts down with nice berms and jumps all the way down - awesome trail!
