I rode Red & Blue loops last night....
During the Red Loop in Dances with Trees, very close to the end (before you turn right to head out toward the Peninsula) there's a tree across the trail that has a medium-thick branch about 18" off the ground. I was timing myself, so I hopped off and ran around it, but it might be something a few strapping young lads coudl move out of the way without needing chainsaws. Just wanted to post a warning since it caught me off guard and was way too high to hop over.
Also, the first...oh...maybe 3 tenths of a mile on the Crazy Beaver loop looks like someone took a bull dozer through it. What used to be a very tight single track through brush and tress is now a very wide and sandy stretch replete with tread-marks about 4' apart from each other straddling the trail. It wasn't bad to ride, but it's sorta ugly.
The Blue Loops are in great shape, fast, no trees, and plenty of room (since nobody ever seems to be out there on them). The Red Loop is fast and dry too, last night was great riding!
What tires should I run for Iceman?
