For land in that area you might check with the soil conservation office in Carlisle County. They might know where some in available. Will probably be able to help you with the tax information also. I just looked up their address and phone number for you.

I grew up in Mayfield and drove through Arlington every now and then. Hadn't been out that way in quite a while.
