I think it's not Pubic Retreads Incomprehensible.
Seriously -- I don't know for sure. Perhaps "Performance Racing Industry? I'll go to the website and look it up. I know that I found it through Google -- by typing in just those three letters.
So, Rick -- the show in Indy? What's it called? When is it? Maybe there'd be reason for us to go there, too -- although our travel calendar is pretty well booked what with racing through Riches/Airtech was there, and I remember seeing a you the end of October, so that'd play into our plans. We went to a show in Indianapolis a handful of years ago. Kent delivered a bike for us from Calif. or someplace, and I best remember seeing a young fellow wearing a 200 MPH Club shirt - and that impressed me and made me wish I had one of those for myself.
And now, a bunch of years later -- I've got the shirt.
