Rode Highland again today - loops A & B. Because of all of the previous hiker/biker traffic, there were spots of ice here and there on A, and lots of crusty footprints to ride through. The first 1/4 mile of A really sucked (due to the footprints), but it got better the farther we rode in. We continued on to B from A.....the initial hill sucked, but then after that it was fine - lots of areas were completely devoid of snow - just like riding in the fall with all of the leaves down. Then when we got a ways in - we found the deeper sheltered valleys where the snow really never melted - we were able to ride DOWN the hills while pedaling, but riding up in these deep snow areas was not really possible. One of these hike-a-bike sections was quite long, but on both ends of it were areas completely free of snow. All in all, it took us 2 hours to get to the intersection of B & C. Because it was getting late, we bailed out to the road via the equestrian trail.....only to find the road a sheet of ice!! We did manage to make it safely back to the car without issue.
FYI, the trailhead parking lot is an ice rink. Except in a few aforementioned spots on A, studs were not needed at all - and would have been a huge disadvantage on the rest of the trail - especially B.
