The guy in some of the E2O photos is Than Tran. He is there off and on as well. My next scheduled event there will be May 9th. If you will be there, look me up or shoot me a PM, I'll be sure to take a few shots!
Nice shots at Edgewater! I'm usually shooting photos at the wall on UMTR nights and other events. Feel free to browse through my stuff to see if you know anyone!

The rear tires are acting like springs of their own....the taller tire has affected your spring rate. A couple of things to help you - add more air to stiffen your tire "spring", shift some weight or add ballast to the rear.
