Don't go unless you can get a mostly private spot. Most tent spots are not private and when we were there some lady walked her screaming baby around the park at 3:00 a.m. until the Rangers told her to get it together already.
Make sure you don't grab a tent spot next to an RV spot.
Super windy but awesome
Silver group is the best campsite for 20+ people. Spacious with several fire rings, vault toilet, no showers but you can bathe in the reservoir and stream nearby.
West Woodside is more private
If you like folks who party - go here.
Most sites are private and it's generally quiet.
