I believe the count of 4 counties is probably correct. Your bet bet would be to call the PGC and find out where they are. From what I gather, a few escaped I think somewhere in Cameron county but I could be wrong. Anyway, the PGC may be able to give you some info. I do know that the 2 WCOs I talk to told me that the PGC want to get rid of them before they get out of hand. Pigs multiply quickly.
