You can in Utah. A bill is pending in the Arizona Legislature. I do not believe you can in Alaska. However, Alaska and Arizona have Constitutional carry.
The bill in AZ is dead as a doornail. Brewer got reelected, and no longer has to toe the conservative line. She vetoed that bill. I can’t drive on certain public streets in Tempe because I carry in my car, and that’s agin the law. Thanks Jan the Great.
