I'm sad the hear that. The WPSA quad terrain challenge (4x4 races) looked like very exciting stuff...a big crowd pleaser for sure. However, those races looked to be extremely hard on the atvs...so much so that the avg. Joe could not compete in then as it would likely tear up the quad (it appeared to be much worse on the ATVs than GNCC races). So unless the racer has a factory sponsorship, then he probably could not afford to race in that series (quad terrain challenge). Certainly no way I would put my quad thru a brutal course like that! BUT...sure was fun to watch them tho!
Happy trails...:)
