Hey, I'm from Kenosha too!
Where do you normally ride? The bike route along the lake? I just have a MTB at the moment, but I'm more interested in road cycling, so maybe next year get a decent road bike...
As far as going for the charity ride, why not?? If it's something you want to do, go for it... and maybe you still have friends/family in St. Louis? If you just want to ride in a group/charity ride atmosphere, not specifically St. Louis, then there are a ton of other ones closer to home... Chicago has several events I know each year, and I assume there are similar events in WI (I just moved across the border from IL about 8 mos. ago...). Check out the Bicycle Federation of WI (
www.bfw.org). There are a tone of fun rides, and competitive rides that they list in their publications.
Take care,
John
