i'm not a very good shot and I don't think my husband will teach me. so far so good on the CD's hanging on ropes and a whole bunch of other line strung everywhere. haven't seen him in 3 days. last time I did he was sitting in a tree over the pond, then jumped down and walked away. I may have discouraged him enough. I can only hope.I figured a shot or two or 30 from a paintball gun would be non-lethal and maybe scare the crap out of it enough for it to not come back.?
