Bodie is a great place to visit, I've been there a couple times over the years. It's really beautiful in an eerie, desolate sort of way. Fascinating history as well. Walking around the town, it looks like everyone just suddenly up and left one day, leaving everything behind.
There's no camping in the state park istelf, but both the Forest Service and BLM offer camping nearby.
During the late spring through early fall, you can drive in along the dirt road. Once the rains and snows start, you have to snowmobile, cross country ski, hike or snowshoe in.
On just about any day of the year, Bodie can be found listed in the weather section of the newspaper as having the coldest temperature of anywhere in CA.
Here's a few photos from Thankgiving last year:
