Not really. Main St, Lemon St, about half of Hoover St, New St, Orkney Rd, Section 8 in the back of Summit Hills, Lincoln West...yeah.

Most of my family still lives in/around Mountville, so I'm still there quite frequently and it doesn't take a genius to notice the steady decline.

Yes, in PA (everywhere except class "C" cities; that is Philadelphia and Pittsburgh) it is legal to carry with your gun loaded and in plain sight. But just try it in cities such as Lancaster and York. You WILL be hassled by the police.
To carry a gun concealed, loaded or not, requires a "License To Carry Firearms" from the county you live in. Concealed includes in your car anywhere (while loaded). It is not considered concealed if it is unloade and either the bullets or gun is locked up and out of reach of the occupents. This is so you can transport the weapon to target practice or the gun shop. The PA uniform firearms code is very specific and clear on this exception for both how and why you can trasnport a weapon in your car.

Also, nowhere is the state can you point a gun in a threatening manor (only in self defence). That is considered brandishing and is ilegal.

i have never been harassed in Lancaster or York...interesting

Do you carry in plain view, meaning that your firearm in is plain sight to the public at all times and not underneath a jacket or otherwise concealed in any way?

depends on my outfit/weather. I have concealed holster (inside the waist) and paddle holster. I have permit to carry. But I was responding to whoever said they are harassed by the police in lancaster while carrying... people just like to run there mouth against the cops...for anything with no proof...just gets annoying
