Was at Elk on 3/23 (Easter Sunday). The place was a ghost town so there was absolutely no waiting. Conditions were what you'd expect this late in what has been a bad snow season. Overall the conditions were excellent. Some spots of ice, which would have been worse if the crowds were heavy. Was told they may be open until 3/29.
Elk has no equal in PA. Sorry, but Montage (or Sno, whatever they call it) is just weak. Camelback is far to crowed with too many merging trails. Blue Knob has no variety and the rest are just tiny, with the exception of Blue Mountain which is nice but too crowded.
Having just gotten back from Breckenridge and Keystone, it's tough to ski PA, but Elk has some decent steeps, good cruising runs, a good quaility of skier, and is a remarkably easy mountain to navigate. Reminds me of a smaller version of Stratton.
Friends in Colorado joke that they've got bumper stickers that play on the old PA state tagline. It goes: "You've got a friend in Pennsylvania...who skis in jeans". I admitted that I did many times.
