Bemis on spiked tires

I went on a 30 minute ride through parts of Bemis today. The trail was a mixture of about 2" of snow and ice. I had 35mm Schwalbe Marathon Winter tires on the Moots and they are pretty grippy. I can turn pretty close to normal on ice. The ride was pretty tiring, kinda like riding in mud, but it was a lot of fun.
