Last night I went skiing for the first time this season up at SnoCrummy. It was very mellow stuff- a slightly tilted parking lot- but I had great because I was out with a friend (Snugtop) and was teaching her how to ski.
She was doing great, blossoming from a lowly snowplow to lovely s-shaped turns with parallel skiis. Everything was going great until a snowboarder bombed down the empty slope, slamming into Snugtop from behind. They both went down.
Snugtop tried to get up, and collapsed straight down. The collision hadn't been that bad, but she'd fucked up her knee. I sent the boarder down to get the ski patrol, and we waited in the snow for the sled. Snugtop went into shock, and was shivering violently. A lift attendent put his jacket underneath her, and I put her in my jacket, but the girl in bad shape, and didn't stop shivering until she'd been in the first aider's hut for twenty minutes with hot water bottles packed all around.
This happened within sight - hell, with throwing distance- of the ski lodge.
I've generally carried a small sleeping pad (butt-sized), insulated nalgene w/ hot water, and belay jacket for b/c stuff, but after watching Snugtop's sufferfest I think I'll supplement that with a jetboil stove & fullsize sleeping pad.
