Hello, yes nowdays alot of people taking medication, just as bad as crack or any other drug especially when them oltimers get to mixing a little boose with it, , not as easy to knock on peoples doors or safe as many think, i live in a small town and just went to ask permission to hunt the county fairgrounds, lady said no, actually i need you to leave now, i was nice she just could not take the time to say anything nice, and i was not on someones yard or something, people are very protective nowdays and really if you think about it. i don't blame them , because the same goes with crazy people coming up to there house, you never know when a stranger could jump in the door and rob you etc, --i will tell you guys something, my friend went up to a door one time, and a guy shot 3 or 4 time through the door at him, the guy was wacked out, he never answered the door or anything, just bam bam bam shooting threw the door, and this is in a small town, the prisons are full around here and i am sure where your at also, you know most of them people are not in there for jaywalking, there is alot of crazy people out there, ---piggman you know this, very sad to hear about your loss down in texas, i hope they caught that guy,------but there is hope for gaining permission, mail the place you wish to datect and ask them for permission, give them your phone number they can call you if they don't mind, safest way i know, good luck to you
