I came to your site via "Stumble Upon", looks like just what I've been looking for. I have been a cyclist for 60+ years and am now retired living in Dolan Springs AZ. Plenty of trails for off road cycling. Nice dark skies for my other interest, Astronomy.
I'm working on a idea for a offroad quad cycle, and a trike for touring. Wedgies are getting too uncomfortable. I have been looking at using bamboo/CF/epoxy frame building methods. Only problem, not too much bamboo in Arizona.
