I was walking around Phoenix Mountains park today, and I saw several signs that said something to the effect that carrying firearms in improved areas was limited to only those with a CWP (at least I assume that is what the portion of the A.R.S. they were referring to is about, unfortunately I didn't write it down or take a picture). Is this a holdover from before constitutional carry, or does it still require a license to carry in these areas? It makes no difference to me, because I have an AZ CWP and a TX CHL, but I am curious.
