I hadn't heard of the Slimey Crud Run until reading this post. The ride is through some great countryside. I just rode through the area last weekend with the wife on our 250s, riding up to Black River Falls from the Evansville area. We then did the southern half of the Trans Wisconsin Trail, which was also great, but a lot of riding over three days on the 250s, looping back to Evansville from Hazel Green.
I may check out the SCR to see what it's all about. Let me know your status and timing and maybe I'll ride in your wake on the way up. I can't commit at this point.
