Yes the night Rides are a blast. I just bought one of those Xenon lights for my helmet and I am having a blast!!! I too work most of the day in my office. I work out of my home, but I try to ride my bike during 10:00 and 12:00 every day. Exercise seems to real help me, I was just curious if other AS sufferers exercise.

Dont let the troubles in your head
Steal too much time you'll soon be dead
So Play

"An error made on your own is safer than ten truths accepted on faith, because the first leaves you the means to correct it, but the second destroys your capacity to distinguish truth from error." - John Galt, Atlas Shrugged
