Well, just walked through the door from my flight home from Los Angeles. Flipping through some mail from the week, and what do I see but a letter from the state of Utah. Opened it up and my non-resident, concealed firearms permit was in there with a letter stating I was approved.
I applied for it simply because it offered some redundancy in other states, as do other permits from other states. To see where your CCW may or may not be good, go to Handgunlaws.us, and click on the state you have your CCW in.
