The park at LL is sooooo much better than ssv. If you know where to go there is pretty unreal stuff at LL. The out of bounds section i have been riding gets 0 traffic. On 2 weekend days there is no one tracking it out, it has cliff drops, pillows, trees, knee to waist deep pow.
However, if ssv would just put their park on a tree'd run, i don't know if i would ever go to LL. I bought a LL seasons pass last year but i think that next year i will be back at SSV now that more of my friends have avy gear.
