Hey guys, I know this thread is old, but whatever. I grew up in the Rosepine area. That being said, a good place to check out be down a the Sabine River area, where HWY 190 crosses the river from Merryville into Texas. As a kid and teenager we were always out there playing in the river and on the sandbars. That's where I'd go, maybe find some jewelry or modern coins, maybe even older coins. If you have a way to find a landowner, I'd also check out the area where the Anococo creek meets the Sabine River (you can find this on google maps). Really old records show there was a Attakapas tribe encampment there. These natives were know to have traded with the white settlers in the area, and may have dropped things, who knows. If you can, I'd grab a kayak or canoe and paddle up river hitting the river banks where you can on one side, and then let the current carry me back down as I hit the other side. Keep a lookout for arrow heads as well. Good luck guys.
