Mebert,Sugar Grove is a haul. Maybe you can figure out a route that has you biking and driving? It's nice to know about local groups. I actually ride through Mather Woods as part of my trip. Gotta tell ya though, I get all messed up in Springbank. I'll have to check it out, but right now 40 miles is a little far for me.
Aham, you might be surprised at the creative routes you find although I'll admit it's hard to find a decent North/South road. Google maps has bike routes now but like most maps, they're not completely reliable. Maybe you should talk to ScottNotBombs about riding north to Napervegas?
Thanks!
