I skied the spring of 2008. Chad Paeglows review of Kirkwood is very comprehensive so I won't go into much detail except to say:
1. It is phenomenally good value. Spring pass was 99 bucks.
2. Lots of the terrain is terrifying. Kirkwood is the place to sharpen you ski skills and learn to jump if you think you're an advanced skier. There are 100s of jumps ranging from Hollywood Hip, a rollover under lift 6 which pretty much any decent skier could hit, to Hospital, a 100 ft cliff drop that gets hit by a couple of maniacs per year on a big powder day. Most people should be able to find a few jumps of their level.
3. There is virtually zero apres-ski.
4. It's a short mountain.
