My familiy and I are heading south on April 7th to Durham Plantation in Union Point, GA. I found the place on the web while looking for riding spots on the east coast.
There's a lot of info on their web site.

Seems like a decent place. They have one Adult MX track and one kid's track. Plus a third track that is mentioned but not described much.
There are also about 40 miles of trails according to the site.
You can rent an ATV.. and yes.. a CRF-250X. Plus smaller bikes. 50, 70.. etc
There's also three lakes for fishing. You can Trap/Skeet shoot if you're into that. Or hunt if it's the season and that's what you do.
There are some MX parks and off-road parks not too far from there. We may check one out if we have time.
They have a bunch of RV hooks-ups (60 I think) and a dozen or two lodges to rent. Plus campsites.
So.. we're keeping our expectations modest and we'll see how it goes. I'll report here after we return. If anyone's been there and can provide some insight, that would be apreciated.
