I'm using a Garmin 62st this hunting season and it has come in handy in many ways. The one thing I would really like to see is property lines on some of the private land I hunt. I do know about where they are and usually keep a safe distance to be sure but is there something I could add to input the lines on my topo map. I'd prefer free but don't mind spending a few dollars if need be as long as it covers the state or even just Northeastern Pa. Anyone know of something like this.
