I had the same experience as Lisa today. Went on a 3.5 mile snow shoe, and it was really hard, just walking on a relatively flat trail. Most of it, you could walk on top of the frozen crust, but in other places, you sank down and had to really work to step up. Usually this trail is 4.3 miles, but my friends were tired, so we turned around and went out for cafe mochas instead...
Hopefully, I will be on my bike Thursday or Friday.
