Not while hunting but I once had my pointer track me down about a mile from the house in town! I had drove from my house in my cj7 jeep to the gas station. About 15 minutes later my dad let her out and away she went. I have no Idea what she could smell but she came right down the highway with her nose down and right to the door of the station. I spotted her about a block out and watched her come. It was amaizing. the only thing touching the ground was the tires. I suppose there was a vapor trail as it was not windy that day.
