The only problems I have heard of with bears and food in the car is leaving a window open a crack. They slip their nails in the opening and pop the window glass I assume. Some people cover their barrels and coolers with a blanket or somesuch when they are in the car because bears will associate those items with a snack but hanging in a tree seems a bit over the top when you have a perfectly good vehicle.

The wood yard is off to the left when you first enter the park. Go past the gate house and watch for the wood shed in the parking lot on the left. Should be bags of kindling and bags of fire wood with an honour system money drop. Self serve camping registration is a small open shed off to the right as you enter the park.

The camping at the far end of the park on the peninsula can be noisy because of traffic on the highway just across the lake. I think that section is also radio free.
