Just a heads up. We've just found this free online system for arranging rides and joining rides. Its basically a huge online list of stuff that is open for anyone to join that you can filter. The site is called www.wagaduu.com and you can use it for arranging any sporting event.
I joined in a Whister ride the other day and met a bunch of new (albeit totally nuts) people. We're going to start putting up all our North Shore and Whistler rides from now on, so anyone can join us.
See you out there,
