To let anyone close to Louisiana know, I was able to race my '85 200x in the ATV class of the Louisiana Cross Country race series yesterday. They are not openly advertising that three wheelers are allowed in the ATV class, however I contacted the race promoter prior to the event and he said he didn't see why not. The promoter actually raced in the four wheeler ATV class and I talked to him at the riders meeting and he was still okay with me racing the three wheeler. Of course, i got smoked by the 450 race bikes and one or two of the 800cc 4x4's (but I was first vintage ATC and had a great time, right?)
The race series info can be found at acadianaracing.com. Its a ten race series.
