My daughter would be out there shooting them with me....lol she has assisted on reducing the population of wild rabbits since she was 3.Um, Yeah....
But I've got little kiddies and they would in turn shoot me for hurting "the sweet babies"
They'll be gone in a few weeks.
Hubby's bb gun is broken, maybe I'll be more prepared next year.... 8)
