So, I know it's snowing and cold and generally un-Springlike at the moment (at least it is here), but this weekend is forecast to be nicer. I'm planning on heading up to Fourmile (north side) to ride and camp (PM for location) this weekend (Saturday morning through Sunday afternoon). I'll probably be bringing an unplated bike only, but there are tons of great routes up there, everything from wide dirt roads to deep sand and tricky trails. You can do some on a big bike but a short bike will be more fun. Weather permitting; cool temps are expected but a lot of snow on the ground would be a no-go. The FS site indicates that all of the gates are open, and Ramz's thread indicates that it's ridable with the occasional spots of mud and snow.
