I have a cottage on one of the lakes north of Harrison, which is in Clare county. There is a big piece of public about 10 miles north in very southern Roscommon county that the locals just call the oil fields. I imagine there is at least a couple of thousand acres of state ground that an oil company runs some wells on and maintains the road system. A lot of oak and poplars with a mix of good size cedar swamps. It gets hunted fairly hard and our population is down due to 2 bad winters in a row, but I used to have very good success there.
There are other pieces of public ground in the area, but all will be hunted pretty hard. I just know this one the best.
