I’m saying excellent because you can ski a loop, retrack it twice anywhere you want, and you’ll have fabulous skiing. The tracks will be as good or bad as you make them. Use rollerski poles. The underlying ground is frozen but there’s a crust that will grab the baskets of your poles, stressing a muscle right on top of your shoulder. This will be today only, try to be there at daybreak. It’ll be gone after it warms up today.
