This is the original park we wanted to have the AR GTG at, but they were already booked. Didn't want to waste my pics, so I thought I would put them here.

Behind the office/visitor center/store they have a Nature Cabin.
They have a sandy beach area for swimming.
Outdoor showers are next to the beach for rinsing off when you finish swimming.
There is a floating marina where you can get bait and rent paddle boats/bicycles, canoes, kayaks & pontoon boats.
When we were there, they were having an antique outboard motor club gtg. Here are some pics of their cool boats.
The cabins for rent.
Bathhouse/restroom
We stayed in Site #5 (handicap) with a ramp to the bathhouse.
It even had an accessible fire ring.
Some other sites.
There were deer that came up to our site each evening around 5pm.
