This is a great park!! Was in Pittsburgh visiting recently and of course we had to take in a baseball game. We're pretty spoiled coming from Seattle with Safeco Field as it's a pretty nice baseball field - however PNC Park is equally impressive if not more so. We bought the cheapest seats but there were enough empty seats that we got to watch the game from lots of different areas of the stadium.
It's a great view of downtown (and a great view of the park from downtown) and nice being right by the river. Even got to see a home run hit out of the park - not just in the seats but actually outside the park. Pretty cool.
