Rode up to Betasso from boulder via the bike path and the connector trail. The bike path has some slippery spots, but is pretty much ok to ride. The connector trail has zero snow - conditions are tacky but not muddy. I came closer than ever to cleaning that one hill at the beginning. Lost it just before the rocks, but at least I didn't spin out like in the summer. The betasso loop itself is in pretty good shape, though there is some snow up there. I didn't feel like I could really let the bike run on the downhill because of the snowy spots - I'm not used to riding that stuff, so I don't know what to expect. Didn't seem to bad though, there were only one or two really slippery icy places.
