Another problem that we need to think about: lack of snow/bad conditions exacerbate the risk of skiing.
I almost ended my season and maybe more a couple of days ago-- my first day in this dreadful dry winter. Was skiing quickly but not overly fast when I caught an edge on an icy patch just as I was transitioning in a turn. Things quickly degenerated and I consciously laid it down rather than struggle. But that didn't end it. I slid 20' to the edge of the trail on the hardpack, and, because the trail is now elevated above the bare ground, dropped over the edge, and then into a gulley and trees without ever really slowing down. Luckily (?) I was on my back and balled up and I just got a couple of big bruises. Head tapped a big birch just as I came to a stop. What finally arrested me was when my ski snagged in a vine.
You can bet I took some time to breathe, test my extremities, and calm down. I haven't been so scared in a long time. It took me about 5 minutes to climb out of the hole, sort out my equipment, and get organized to ski -- very slowly -- back to the lift.
I'm not saying this couldn't have happened anytime....but icy hardpack, unforgiving trail margins, and exposed roots and trees make for a more-dangerous-than-usual environment. Be careful out there.
