In the 30's and 40's they base grew and many towns were removed. Those places will never get a hobbyist coil swung over them. One of my ancestors lived where the Godman airport on post is today. My small town is rich in history. I rarely go anywhere but here to detect. A Sanborn map would be a great tool for me to use at times.
