Favorite COE park in your state

We saw a great one close to Hannibal, MO, not sure of the name, huge sites and mostly flat. Not our home state but we also really like Prairie Creek, just outside of Rogers, AR. It's hilly but really pretty, on Beaver Lake, decent sized rig sites are 73 - 79 only. There are other long sites closer to the lake but are on a tight loop or you have to back uphill to get in them. There's another COE there, Horseshoe Bend but it's about 12 miles out of town. We stayed at Dam West in Carlyle, IL this year, nice large sites on the lake with W & E. The spillway has big sites but take no reservations. Not many restaurants in the area but Wal Mart is right down the street.
