We are working on trails. We have cleaned up all the ice damage. Peregrine and Middle Blue Jay had substantial damage. And now, trail mowing has started.
Carry a knapsack. If you overdress you can carry your extra clothes.
When Nordic skiing we all warm up quite a bit. So that makes it a great sport for cold weather (No chairlift). Sweating does happen. A dry shirt to wear for your second lap and/or to wear home is really nice.
