I suppose to start with, the NRA of course.
I was a bit dissappointed though that they were of ZERO help when I recently contacted them to try and help get FL law changed (see other thread somewhere here about carrying near Florida hospital's being a felony). They told me to get a lawyer although it's more of a sending letters to state reps kind of situation.
Anyone know of other orgs? I'm still agitating to try and get FL law edited and would love to know who to approach.
