If you are looking for a dollar menu type deal then I think I have your answer, its over hear in Andover, NH, its Blackwater Ski Area
http://www.nelsap.org/nh/blackwater.html
Its not huge but last time I checked it cost under $10 bucks to ski all day and they also have lights for the night. I do not know if that is the resident rate or not but the school pretty much just lets other folks ski there because they are nice.
Could practice your jumping, downhill racing or cross country ski for free on our rail trail that passes the base of the slopes, (it goes right accross the end of my road, so if your on the trail Less, give a wistle on the way by.)
