One thing to think about when visiting PNC is that there is many things that can be done in conjunction with the trip depending on the length of trip. Our trip was a baseball trip that did not allow for much time, but because of Pittsburgh's proximity to other large cities we were allowed to travel to Cleveland and Cincinnati to enjoy games in a three day span. The same most likely can be accomplished by heading east as well with Philadelphia just on the other side of the state. There is much do do in this area of the country so don't limit yourself to just a game at PNC.
If you are a sports fan visiting PNC you might also consider working a trip that involves catching a Steelers game at Heinz Field. Although I have never seen a game there in person it is sure to provide excitement that only a steelers game can and the stadium is beautiful from the outside. One thing that really makes the area neat is that PNC and Heinz Field share a parking lot and are both located on ther other side of the Allegheny River. A special environment for sports fans has definitely been created here.
