Thre are 18 of us headed up to Steamboat for 4 days of skiing. They are also having a winter carnival up there and one of the events is a mt bike dual slolam race on the ski slope. So I heard that best way to stay upright was to put some spikey tires on your bike. Too cheap to by some real ones, I made some. I tested them a bit on the frozen snow patch by my house, I think they will work pretty good. The race is Thrusday night, so I will let you know after the weekend.
On the single ply tire I could turn it inside out and put the screws in pretty easy. I just picked a random pattern that should allow at least one screw touching the snow at all times. I would prefer more, but that would be too many screws and too much weight. This one will be my rear tire.
We made our way into the trees to find that it was almost waist deep, but with no bottom but rocks and down trees. 


So, lots of pushing and finally made it past. Only to struggle with one that I had made just fine earlier. This one was pretty tricky, it was so far to the side of the trail I could barely get it back onto its wheels without losing it down the hill.

These things felt way steeper than they look here.
The way we unload the flat bed. Waitin' for one of those boards to break.
