Yes i have.
Two years ago after our season here in Utah, myself and two friends spent 3 days there. Two days at Hood Meadows, and one day at Timberline.
Hood Meadows aka MHM, is the better of the two resorts, alot of differant terrain. Timberline, was in my own thoughts mostly groomers on a glacier. But still fun.
Snow conditions were way differant that what we Utah skiers prefer.So pay attention to the snow reports there.
Also both resorts do put thier upper mtn lifts on weather hold often.
Both resorts are located 65 miles east of Portland. But there are hotels in Goverment Camp, Or Which you pass thru on the way to both areas.
