Mountain Creek was my home mountain for decades... I even went there when it was called Vernon Valley (or some shit like that).
I finally grew tired of the endless beginners clogging up the mountain. I thought a dedicated South would fix it, but thats still clogged up with beginners. The just love sitting in the middle of runs or bottom of jumps.
Now I go to Hunter. If you stick to the Hunter West black diamonds, its totally empty including the new high speed quad which is deserted. Its worth the extra hour drive for me.
