Unfenced - Land for sale that actually borders public land

Hi Product Hunt! I'm David, and I built Unfenced. In the 1980s, my grandfather and his brother, along with a few of their friends, bought roughly 240 acres of wooded land in the northern Lower Peninsula of Michigan. It backed up to thousands of acres of state land, so the property line was never really an edge. You could walk out into the woods and just keep going. Years later I went looking for land of my own in the Poconos and wanted that same feeling. I found a parcel that borders state game lands, but getting there meant reading listings that said "near state land" and then working through county GIS maps to see whether a property actually touched the boundary or was just somewhere nearby. Unfenced does that check for about 700,000 U.S. listings, every week. It takes each property's county parcel boundary, compares it with the USGS map of public land, and shows the ones that actually touch it, with the shared boundary measured in feet and drawn on a map. Each property also shows: • how much connected public land is behind it, and who manages it • its elevation, and whether a mapped road reaches it • its FEMA flood zone and Forest Service wildfire hazard (new this week) You can search by ZIP code and distance, browse by state or by national forest, or just pan the map. It's free, with no sign-up and no cookies. I'd love feedback, especially from hunters, homesteaders and anyone who has bought rural land: what would you want to know about a property next to public land that the site doesn't tell you yet?
