When I became a full timer I went to apply for one and after talking to the instructor and being informed of all the different laws each state had about carrying and/or just having guns in the MH I opted for not doing it. How could one possibliy be up to date about the regulations for each and every state they traveled thru? Just saying. I didn't want to have to sit on the computer researching the next state I was about to enter to see if I would be legal on that day. The OP's post shows just that.
