good to know, we have some on Willie Powell Rd., Sunny South, and Anne Manie off of 32.
We are N of you on 5. Next road N of Gamble Rd. We take pigs all the time to the Gamble's and other assorted locals at the body shop/auto repair/burn barrel location on 5. Take some also to the Roadhouse store/caf� just north of us going toward Catherine.
My Dad's family is from Arlington and most of the advice you've been given is correct. Don't leave anything and don't lock your camper. Contact the pastor of a church near your camp and ask for the names of some locals you can make a small donation to (meat, disk up their garden, help them somehow) and you may have an easier time of than some who wouldn't roll down the window to speak to them or stop if they were broke down.
People are people. There are good and bad. Get in with the right good ones and you may have no trouble. Met a guy who had several camps in downtown Lower Peachtree and had NO problems (allegedly) but they had a local who worked for them full time as a caretaker.
