If you really want to try it, make sure it's a weekday, and NOT a school holiday. Or you'll hate it like the rest of us!
All my experience at MC were before they converted south mountain to terrain park. So I thought the terrain was decent for its size. It's just the crowd that's the problem. I'm not even talking about the crowds on the slope, the crowding BEFORE you even get to hit the slope was enough to drive me out of there! But now with the terrain park, I have even less reason to go there.
Part of the "hate" has to do with the relatively easy access to far superior alternatives in the Cats. Most of the Cats' mountains are, in my opinion, are just a tad below the critical point of crowdedness. MC is above that critical point, which makes it impossible to enjoy it.
