Afton is a blast if you hit it on a weekday morning. The lifts are still slow but usually no lines at all. and they still usually have 15 of the 18 open.
My best day day of riding was at afton last year on a wedensday morning right after we got 8" of snow. nothing had been groomed, it was 28 and sunny, and 90% of the time we had the whole run to our selves.
