We had a guy (with relatives in OK, btw) who released 50 about 20 mile north of me. A year later he released 50 more. There were sows and pigs everywhere. I shot 4 out of the combine. The two sows had 5 pigs each. "They" said you have them now - you'll never get rid of them. "They" never heard of Louisa County, Iowa.. Took a couple years - done deal.. Tell these boys, "Isis is good to eat, limit is one, season is closed." We'd have them wiped out in a week..
