OK, so I went to Mountain Creek today, and I didn't ski, but I walked up the mountain and surveyed the park.
If you like rails, then it's in really good shape. You can ride rails basically from top to bottom. Good flow, nonstop.
They have three jumps. One is small and two are medium-ish. They aren't the best jumps, and they aren't the worst. The small jump could use a more kick and a longer landing. The medium-sized jumps could use some more kick on the take-off; otherwise, their landings are nice.
They are hurting for snow, but you can tell that they've made a lot so far this year: the trails that they do have open are well-covered.
Man, they need some real snow just to make it feel like winter.
