I lived up in Michigan for four years. There were some nice older sites around, but like yours, were still in use in modern times. The result, lots and lots of can slaw and tabs.

That basically hits the nail on the head. You would have to just buckle down and dig all the junk out, as well as the goodies. If you have an area like that that you can do a LOT of digging at, try staking out a small area, say, 10 x 10', and just make a day of it, literaly digging everything that hits above iron, regardless of depth and size, and some of the bigger, shallower iron hits as well. Unmask the test plot, and see what's beneath. You might get something good, then again, you might not.
Maybe you can research some old "rural post offices", that were usually operating in someone's store, or other businesses, like a sawmill, or a railroad depot that's out in the sticks a bit. Lakeside resorts are great, provided they haven't been covered with modern houses. If you have a water-proof detector, try hunting the old swimming area for a lakeside resort. You can also try to find the old swimming holes. Here's a good website that can help you find those:
