Sheila, I know there is some out there. One of our club members just bought a piece in near the Alabama and Georgia lien and is looking at another. My GUESS is it would be easier to find open claims in the western states than east of the Mississippi. I have been looking at pace I know there is gold and then using Google earth to find roads and pieces of property along the same creeks. It was my intention to knock and doors and ask if I could prospect there. But I think if you drove in the area , you might see for sale signs, or call real estate agents and ask what is for sale in the area. Go look at it, see if it might have potential.
As far as long term camping on claims, Join the LDMA
Their claims are open to up to 6 months stays at a time and the people can't be nicer.
