Hi Freckles
I will reply since my other half can not remember where the campground was or how many times we camped in the area.
We stayed at Interlake Rv Park, it was nice that the campground was some what close to the aerodrome, however it is NOT big rig friendly.
We stayed at Brook n Woods, this park is up the road a piece (Elizaville), however they have a great open section that it is impossible to hit anything and the section is all 50A full hookup.
The Aerodrome is a great place, all pre WWII aircrafts and other old things. Oh and Biplane rides, now that is a great (open cockpit) ride. The other half remembers that RIDE, ask her
