Now as far as people's home as well as places posted with ghost busters type signs. I was told by an instructor that all they can do is ask you to leave or un-arm and you have so or it's tresspassing.
Have fun in New Orleans. Don't dress like a big ole Texas or locals will see it and try to take advantage. Pan-handling is really bad around the tourist areas. If you look like a tourist someone will ask you for money or try to hustle you every 20 ft. Additionally don't take ANYTHING from anyone off the street. No matter how "free" they say it is. Check out the WWII meusem and a swamp tour if you can they are both really cool. If you don't like crowds hit Bourbon and the Quarter on Sunday and youc an avoid the crowds and drinks are cheaper.
