Sounds like a great place to hunt. As he said, watch for slave tags. I would guess they were brass or copper (?) so key in on whatever they are made of in terms of target conductivity. Those tags are worth big money. I remember seeing one metal detected on the antique roadshow and it was appraised at thousands.
Be careful about those ticks. Use some good bug spray like Deep Woods Off or Repel, and not the regular Off as I find it doesn't work as well. Spray your shoes and ankles and pants legs for sure, but also up under your shirt at the waist line and around your kneck and arm pits, so they can't find a way onto your skin without crossing the bug spray.
Deer ticks are the only ones that carry lime, and those are tiny little guys about the size of a mustard seed. The bigger ones are wood ticks, and while they don't carry lime, they can carry other nasty bacteria or diseases such as Rocky Mountain fever. I've never got a deer tick on me, but I have got wood ticks on me and one was embedded on my thigh. That was before I started using bug spray. They like to hang around water for some reason. Probably to wait for an animal getting a drink, but they can be anywhere. Luckily in north east ohio I've never got a tick on me, but 100 miles south where I fish and hunt they are as thick as blades of grass from about April to the end of August, so I try hard not to walk through even grass down there during the summer fishing and stuff, even if I've sprayed up.
