A few years back, a buddy and I got all the RR's (at the time) in a summer. I think I put on over 5000 miles in the State to do this. It was a blast. We started in the spring doing 10 on a 32 degree day raining up the side of Lake Michigan and into Door County. Wife did some with me also. This is just plain a cool thing.
I can explain it to you, but, I can't understand it for you.
