4 -10" of fresh, untracked and unpacked, snow is optimum. Deeper or wind-blown snow is tougher to get through. Snowmbile packed snow is surprisingly difficult!
An advantage of kold cutters over studded tires is they work better on frozen snow and solid ice. A disadvantage is that they loose their sharp edge on dirt
The conditions INCA referred to and photographed on 12/9/06 were excellent! as the ground was not even fully frozen.
Hoping for more accumulation for next weekend, as I'd like to go again - it's good clean fun! YEEHAA!
