Every ski area, big or small, whether you ever heard of it or not, has some seriously steep terrain. See for example,
http://www.bigskyfishing.com/Montana-Info/galleries/discovery/maps-discovery-backeast.shtmI did not ski these but saw them from the lift. Much of the bowl is downright scary. I'd want 2 feet of powder before dropping in. Then, of course, there is the concern about avalanches
It is a very bad snow year by Montana standards, every day it is 50 deg in the valleys which are all brown and bare. At Chief Joseph Pass XC area the snow is about 5 feet deep and the skiing is beautiful but the locals say it should be 12 feet at this time and they are complaining that winter is over. There seems to be no prospect for change in the next week at least.
Missoula, home of the University of Montana, has an interesting cultural scene. See,
http://missoulanews.bigskypress.com/missoula/im-an-indian-too/Content?oid=1730417The interstate between Butte and Missoula has a half dozen billboards advertising the upcoming Testicle Festival, that's as in Rocky Mountain Oysters.
Distances are big here. I was told that both Lost trail and Discovery are near Missoula. They are 90 miles and 75 miles, respectively. It must be 400+ miles from Big Sky to Whitefish.
I could not get a beer in a brewpub after 8 PM, state law.
Every town in Montana has at least one fly shop, usually with a rainbow trout on the sign.
The people here are great.
