From what I read you can carry concealedin any countyin the state of PA. There are certain buildings you can't go into, but that's it. In Philadelphia you are not allowed to Open Carry, if you have a concealed carry permit it's no problem but I think the gun has tobe concealed. A lot of people don't realize you can open carry in PA without any kind of permit. Check out
www.packing.org for each states laws. The NRA is also a good place and
www.pafoa.org PA firearms owners association. I live in Pike county and I think the whole process took about 1 month.
