We stayed in the primitive area which wasn't crowded at all just after labor day.  The sites were nice and wooded with lots of privacy.  It rained most of the time we were there so we didn't get to explore much.  Tried to walk down to the lake from our site, but just got to the top of the cliffs on the lake.

The automated pay system insisted we pay for 2 nights since they considered Thursday to be a weekend night.  This is just silly.  Thursday is NOT a weekend night.  

We only spent one night due to the rain.
