I'm beginning to get back out for a little predator calling now and then, although I've had to make some changes there too. Since I can no longer walk far, I've had to adapt my calling procedure somewhat. Also some of my old "hotspots" have become so over grown with brush and small trees that they are no longer practical to use. I'm experimenting with calling directly from the pickup, or at least very close to it. The attached video illustrates that.
When I shot this, I was sitting on a camp stool right in front of the truck. Bear was in the cab of the truck on the seat, and he could see the foxes, which is why you can hear him bark. An electronic call was placed a few yards down the dirt road where I was parked. The foxes left several times, but I would change sounds on the caller (remotely) and they would come right back. I played with them for about 15 minutes, but they were so active that it was hard to get the camera on them. This short video is all I came away with.
