uhm, unless you want a 20 mile or so long road ride, that you have to do with a mountain bike cause the gravel along gross resevoir sucks, I'm going to go with no. its like, a 2000 foot climb or more from boulder to the top of flagstaff. As its been said, the best rapids if you aren't into the big stuff, and even then its the longest stretch of fun rapids, is below walker ranch. eldo canyon trail is no bikes, and I bet there's a lot of snow on the trails over there.Hey, does anyone know if the shuttle on LSBC is bike-able? I guess there is a trail along it but is it good to go?
