when walking my dogs in an area like that I let them off the leash, my dogs are fully trained and listen to me 100% of the time. If they didn't I wouldn't let them off the leash. I have had bikers, horseback rider, quad riders, hikers, and neighbors walk into my sets when calling during the day..
I was calling once on private land when a home owner across the street shot a shotgun over the top of our heads, I guess he was trying to scare away whatever was killing the grey fox pup. I got in the car went over to his house and asked him why in the world he just shot toward us.. (not that nice though). I was hot. I went back the next day and spoke to him, he said he though there were bears or coyotes killing a deer so he wanted to scare them away. I haven't had a problem since at that property..
