Walking sounds great to me. I ran 3 miles this morning and now will hit the airdyne for an hour. I can see the value- the thing just scares me to death. If you want to live on the edge you can join me in the bottom of the Grand Canyon in September <img src="/ubbthreads/images/graemlins/thumbup.gif" alt="" />. You will get all the thrills - spills etc you might want. I am thinkin walking or bicycle as we like having you around please <img src="/ubbthreads/images/graemlins/thumbup.gif" alt="" /> <img src="/ubbthreads/images/graemlins/smile.gif" alt="" />
