As people said, it really depends on WHAT part of PA you are moving to.. here is my area:

Lehigh Valley - Allentown, Bethlehem, Easton area

Do you see a lot of dilapidated buildings everywhere?

Not everywhere, but usually in our historic districts. Some of our 1700 era houses are just ruins, lol. Any dilapidated building NOT historical, is usually only there because the owner is holding out for millions before allowing it to be demolished and converted into high end condos or stores, etc.. When land value is so high as it is in the Lehigh Valley.. few old buildings are left to rot without good reason.

How safe is it?

As safe as anywhere in the US. Just keep an eye out for 6 year olds with loaded handguns
and you should be safe.

How are people attitudes towards minorities?

In my area, we tend to have a strange way of keeping our racists all living near each other. So we have some racist areas, but that makes the majority of the other areas 100% non-racist. For example, in the Lehigh Valley, one town is a well know racist hotbed (Catasauqua) whereas everywhere else is super accepting of all people.

What do you guys enjoy doing?

Everything and anything. You got the local rivers, lakes, waterfalls, and hiking trails. But you are so close to NYC, Philly, and even Washington DC, that you can do pretty much anything you ever wanted or imagined. Location, Location, Location.
