It must be the PT parties attracting them. I found a german shepherd the other day. Friendly as can be. It had some sort of electronic collar but no tags so it went to the police station to wait for an owner. If my stepdad weren't around we'd have kept it until we found the owner, but the police station has a holding kennel for strays and they take good care of them until an owner shows up or until its been long enough to go to the shelter.
