Having never been there, and wanting some place new to go, I ended up at Orion Oaks with some friends today. We rode most all of the trail, and practically all of it was dry, or just a slight bit soft. The only mud we encountered was in the far southeast corner, right along the lake.
The trails seem to be nice beginner-type stuff and I think I'll be bringing my girlfriend here once I get a bike for her to try.
