A group of us put in about 4 hours at MD on Saturday and it was great. The snow made it extra special fun. When I lived in Jefferson (until 1997) I used to ride there almost EVERY time I rode. Over the past years I've only been there a handful of times, and I got to check out all the "new" stuff this weekend. (But only the "legal" trails, of course.) It was a lot of fun and we hit almost every trail in the park. If you haven't been there in a while, I would suggest checking it out again...some of the new trails make it seem like a different park.
