Off topic just a little bit more, on the subject of groundhogs. I use a large have a hart trap to catch the groundhogs and then have a place twelve miles away that the owner don't mind me dumping them at. All I do is set the trap in one of their paths they run on or right in front of their hole, with no bait in it at all, and they waddle right in. Usually within a day, caught four this year that way that were decimating my garden. We use to shoot them, but getting soft, I guess, and my daughter gets a kick out of catching them, though I grossed her out on the last one, which was a big one, when I told her it might make a good supper.
Only thing is that when they are in the trap, be careful of sticking your fingers too close, some of them get pretty ornery in the trap. And put a garbage bag or something under the cage when transporting them. My daughter likes it when I catch the groundhogs, she gives them water from a water bottle and feeds them before they go to their new home.
