Mt. Baker Ski Area 2005-06 season. With a 200 inch base, Mt. Baker is a good choice. Actually most places should be good for spring skiing. Crystal will stay open through March.
There are bunch of good places to stay that are quite reasonable for an overnight. Say leave on Sunday, ski in the afternoon, then all Monday and back on Monday night. Some are pretty nice.
For instance the Canyon Creek “Chalets”:http://www.canyoncreekchalets.com/ is 35 minutes wawy and looks nice.
