Is it crowded on pow days? Might have to plan something there
Kirkwood is never "crowded." It is so big, and so far off the lake, that only the serious skiers/riders tend to go there. You don't get hung up with noob families, because it is a pretty intimidating looking mountain. The main areas look pretty scary to first-timers.
I have a Kirkwood t-shirt they sent me when I was designing their e-mail blasts a few years ago, which says "If you find the trail you're on too crowded, pick another one until he's gone."
That about sums it up.
