Go online... and be ready to keep going out and riding to find the kind of riding that works for you. It's really hard to communicate what a ride will be like - there's a real tendency to want to welcome people... but if everybody but the newbie is a seasoned rider, they tend not to realize when they've worn a person out! Even "beginner" rides can get this way because beginners iwll keep going to the ride... and they aren't beginners any more.
I've heard Wisconsin is an awesome state for cycling.
