Hallowseve,
Maybe you should put together a small investigative team of your own. You and a couple of friends. A video cam, a digital cam, a 35 MM cam, and a couple of recorders should do it (other equipment emf meter, digital thermometer, etc. are icing on the cake). Sit down and think about what procedures you would like to follow to get the desired results and don't forget to provide protection for yourselves both before, during and after your investigations (prayers based on your own belief system).
Think of a name for your team (research the web to make sure someone else isn't using that name) and put together a letterhead with the team's name. Then when you hear of places like the restaurant, where its haunted area is not public, you can write the owner to introduce yourself and to ask for permission to do a small investigation. This might get you in the door because it sounds more professional and not like you're just any curious tourist.
And, I'm sure you wouldn't do this but for the benefit of everyone reading - Please don't sneak in cameras where they are not allowed and never investigate any area without the owner's permission. It can get you into big trouble - if the spirits don't hound you, the law will.
The following site has hauntings in Pennsylvania and I noticed several in Pittsburgh. They are in no particular order so you'll have to scroll through to see if anything catches your eye.
