While I was there, they closed off the Quail Run section.

The Deer Ridge section and all others will be open. They closed the Quail Run area because they get less business during the winter months and it gives them less area to patrol. The trails are still open in the Quail Run area though.
Just remember to ask for the Deer Ridge section. Prime sites on the lake: 56, 57, 58, 59, 66-75 (Any site across the road from these will give you bit of a view of the lake>) Also,
I notice that a few sites, back-up to the playground. Unless you like that much activity around your campsite, be sure to ask at checkin if your site is one of these.
Merry Christmas!
