Just wondering if any of you are going to Oroville for Memorial Day weekend and will be hoping to get a boat-in campsite? I'm told they are first come first serve and was wondering if there is any chance in hell to still get a spot if I go out on Thurs after work?

Thurs. should work for you. Bloomers fills quick. Ask the park rangers if you're putting in at the dam. They usually have a pretty good idea of how many sites are left and where.
