Sick parks, not too crowded
short runs, blacks are a joke
Moonstone is a phenomenal place to ski park, but do not waste your time if you are only looking for downhill. The runs are all quite short and every black is the equivalent of a blue anywhere else.
They have two terrain parks, the junkyard for beginners (I use the term loosely as it includes a halfpipe and 30 degree jumps), and the outlands for experts only. The junkyard has an air bag (costs extra), ~7 kickers, ~12 boxes/rails. Only grip about the junkyard is it's a bit short to ride through. Outlands has elevated rails, huge kickers, etc...
