The trails is hard a a rock and good to go for riding. That said the snow was extremely wet and is now ice. Riding is fine if your tire pressure is not too high or you go to fast. Studded tires are not necessary but recommend.
If you don’t have a set talk to Andy down at Straight River. The ridge line could easily turn into a skate rink if we get a couple of warm days. Enjoy the ride, OTA.
