Mantree, I'd give an arm and a leg for a 100 mile ride starting in Fort Collins. But I'd get out of town just as quick as I could and up into the mountain roads. I have been twice with my CB to Colorado. I have been drooling over the COBDR ride,

It might be too much for my tired old self.
Here at home, I live in suburban Detroit, and I don't ride around town, I don't ride crosstown, I get out of town, two or three counties away into the farmlands, along the rivers and around the lakes, through the state land. Just trying to make a safer ride.
Yesterday, my son and I had as nice a ride as can be had around here. 140 miles through the countryside, the weather was perfect, and most everybody had picked up and went north for the long weekend.
