.... Keep in mind legally carrying in PA with an out of state permit does NOT cover you in a school zone. So if you visit PA regularly, it would benefit you to have a PA LTCF.
Interesting point on school zone which I thought only applied in a state where you are a resident, however the US Code says that you have to have a license in that state. So @mrjam2jab's advice is well taken; let's keep the Lancaster sheriff's office busy collecting $20 from DE CCDW permit holders. BTW, most of the language below makes my head dizzy.
