Hi Mountain, I was just up in AK last summer for 2 weeks. They are a constitutional carry state so any US citizen is within their rights to conceal. As for seeing others carrying, I don't think I saw a single person with a gun. I was on the Kenai Peninsula around quite a bit of tourists, though. I kept my Glock 23 concealed on me almost everywhere except the bar. Check out the laws before you go.
