You may never have gotten a picture of the Big Buck if your Grandpa hadn't moved your trail camera?Is the fence line still there where the camera was.....maybe the Big Buck is crossing right there along that fence row?If it is still there I would pull the top strand of wire down,tie it off to the next strand so the Buck can cross it easier and set your camera up to see if he is crossing there...You may get lucky and have accidently found a good spot to set up and hunt?
