We are in PA and are leaving Sunday for a week in Northumberland PA. We also do not have AC. Looks like the worst of the heat should break by Monday so it might not be so bad. I am figuring if it is too unbearable I will ask at the CG office if there are any other sites that are more shaded than the one we are booked for right on the lake (which does not have much shade. I did get the MPI blankets for the bunkends and will attach them with binder clips. I also have a few of those really thin emergency blankes in the camper so I figure if we need to we can do something with them to cover more of the southern exposure to keep the sun out. We have 2 fans. I am sure it will be very comfortable to sleep but I worry about the daytime since we are taking our Siberean Husky along and she is not fond of the extreme heat. She does enjoy laying on the bunks with the fan blowing though.
