Please change your check out time to 1:00. 4:00 is WAY to late. Talked to many campers and 95% also wished it was earlier. Seen MANY campers sitting and waiting for their spot to open up. 4:00 is to late to start setting camp up after you have paid for that spot..thank you. Again, please consider this, as we LOVE THOMPSON CAUSEWAY!

We were there Monday through Thursday, October 5-8 and really enjoyed our site # HP118 with nice cement parking spot, water and electric hookups. We were facing the river and close to the forest edge. The birds were chirping, nesting and flying around in the tree. We could hear fish jump out of the water about every 20 minutes. Sunsets were beautiful and colorful. We walked on island trails and rode our bikes from there to Fulton. It was a great visit.

Why do we allow some campers to have lights (bright) on all night?
