Check with local chamber of commerce, feed stores, lumber yards, etc for large places. I have been running bow hunts n & w of Fannin on 20 acres place that has been feeding year round for 5 years, with good success. One of the wardens came by last weekend and said there were 10 groups hunting that 2 miles of road, all places are 10-50 acres. Good luck.
Land prices in that area are dropping like the oil prices.
