Was out riding on the lake Wednesday night. If you stay on places where it's been packed you're ok but if you get to spots where it's not packed or wind blown you can expect crusty snow then slush underneath. My sled stayed on top of it fine but when I would stop and check for hardness I would go through to slush in the deeper spots. About a foot deep. I will say it has greatly changed since last weekend. A lot easier to get around. Bring a shovel though, you may need it.
