Have heard of this out west but not here in the east. May just be a matter of time I am sure but can't think of anything against it for the most part. For us hear I guess if you fly around, find a deer, you still have to fly the plane back to the airfield, do all your post flight crap, then hop in the truck and drive to the nearest location and then hike in. Animal will probably be gone from that spot by then I would think.
