Jeff of PA,
A really big thanks for posting. Your post got me to thinking about possible stage coach posts and routes in my area and after a short search I found a large amount of information on the net. Dropping into this rabbit hole also led me to discover a site with a map and descriptions of long destroyed mills in my local area from the early to mid 1800s - looks like I will be doing some door knocking next spring to get on some new sites. Also, folks might want to check out an app called onX Hunt. The app provides maps of your area with property boundary lines as well as the names and addresses of who owns the property. I originally used the app to track down owners of property I wanted to fish or hunt on but have expanded my use to find the owners of fields I was looking to detect. Unfortunately there is a fee of $19.99 a year to use for each state map or $99 for maps of all of the states. They do run discount promotions on occasion so folks may find a cheaper solution. Sorry about the rambling and thank you again for your post. Good luck with your hunts. Walt
