Check out the SEMOW Lawn Racers Mike...
http://www.semowlawnracers.org Great bunch of folks racing there, guys and gals, pretty much a class act in all respects. They make a lot of the local parades as a group, have a nice track set up and draw a real respectable crowd, donate a part of their proceeds back to local charities.
Their forum is linked on the website, jump on board and chat with them a bit.
