Great ride out there this morning.
Some areas are a little icy, some are flat and fast, but most trails have about a 1" crust to break through. It makes it a pretty good workout. Even the little hills felt like big ones. If you live in the area but don't bother to ride Orion Oaks because it's not technical enough, give it a try now. Let me know what you think.
I didn't use studs, but I aired the tires down to "squishy" to try to keep afloat above the crust. Also left the clipless at home in favor of platforms. I think some of the icy spots can bite you.
Anyway, have fun and get out there!
