OK, so you're in the Pines, and not too far from me. I have that sand as well, though mine might not be as bad. Over the years, I've added a ton of horse manure, leaves, old straw, hay etc. It's done a lot to improve the soil. My hubby tried the raised beds, but for me, they were a pain, so I went w/a semi traditional garden. I no longer rototill it, but add all the leaves I can and just let them compost down. The one thing I won't add is the old plants. I either burn them, or haul them to the local compost center.
I'm guessing that the soil you have is more acidic, so I'd say check your pH, and if needed add lime. Or, if you have a wood stove or fireplace, add the ashes. And, if you haven't already, fence in your garden area to keep the geese out of it!
The Pines are a good area for blueberries, so you should be able to grow them fairly easily, or even find them growing in the woods near you. In the fall, look for Russian and autumn olives growing near you. I've never made it, but people make jelly from the berries. They're higher in lycopene than tomatoes. You can also look for things like persimmons, mulberries, etc growing near you. But, don't eat anything you're not sure of! If you're not sure, post a pic on here and someone will probably be able to help you.
