Yes, you can open carry, too. Two Pennsylvania Supreme Court decisions state that you can carry openly (even in Philadelphia since you do have a recognized license).
State law does not make open crry illegal, therefore it's legal.
Don't carry in state parks or court facilities. The Capitol Complex in Harrisburg is supposedly off-limits, too, likewise with school (K-12) property or casinoes.
Bars and stip clubs are okay (possibly in more ways than one).
