Dave Smith Motors (large internet dealer) is located in Kellogg, Idaho as well. They generally will 'donate' a free day every couple years when the snow is good and people aren't ready to be done skiing.
Gondola boards at 8am, lifts (1 and 2) run from 8:30-3pm. No services other than BBQ and beers outside at Mountain Haus, as far as I know.
I'll be there (obviously), anyone else going?
It will be 80F in town, so probably 60-65F at the top... sounds like shorts weather to me.
