The above link should help. I saw some trunking in the area like state police and a few others but I did not see anything digital. You are close to N.O. and I did not check there so cant be sure but I feel most trunking scanner will do the job. If you want Milair then the choices are a little smaller. You will have to decide what you want to listen to. I use a bearcat bc396t as it will go to the frequencies I want to hear. If you know what you want to listen too get the scanner that will listen on the frequencies. Hope that helps. GOD Bless.
