Spend $26 and get a Pennsylvania non-resident permit and you pick up PA, ND, GA, MS, LA, TX for a total of 32 states in which you can legally carry. The only states that Florida adds that PA doesn't is NV and AL. Hardly worth the additional $90+.
This is getting harder and harder to do. Denny Nau in Centre County is issuing OOS licenses but almost no other Sheriffs are. I went through a list of Sheriffs at pafoa.org that supposedly issue OOS licenses and checked it against the Sheriff's websites and almost none still do.
