Consider CA Hwy 88 to Carson Pass. Glorious high mountain terrain and good XC skiing, with the added advantage of close proximity to the Cutthroat Saloon in Markleeville (when I was your age the saloon had a sawdust floor, spittoons, a real honky-tonk piano and a sign on the wall that said "Buy your fag tags here"). You'd also be real close to Grover Hot Springs where you can sit in a 104º pool while it's snowing on you. Good way to recover from several days of skiing and camping. And if you'd like a little down-hill skiing, Carson Pass is real close to Kirkwood ski area.
