Iowa is one of the few ‘may’ issue hold outs.
Fortunately in this county the sheriff is retiring and the main Dem candidate and the only Rep candidate are on record saying they will ease up on the silly restrictions. It will be nice to be able to carry other times than just when I am out of state visiting folks. Additionally Jen and I are going to get a Utah permit soon so we both will be legal in even more states.
Check the laws of the other states, and see if they have reciprocity agreements with your state. That way, your permit is automatically good in another state.
