If you've got a ride you'd like to share, I'd be dead grateful if you'd be willing to send it to me to pop on the site, as would the people who could then read about it and check it out. I'm also especially interested in magazine routes I don't have yet.
At the moment, the best way to submit a route is by email. Drop me a line to firstname.lastname@example.org with a name for your route, and some reasonably detailed directions. If you've got a gps file of some description, then even better! Just attach it to the mail.
