I dare say that's prettier than even Wrigley Field. Sure, getting rid of those support posts will make the view better, but that's just beautiful. Love the gallery on top!

We lived in Pittsburgh in the late '50s to 1961 and my dad took me to one game around 1960. We were middle deck, closer to home plate than first base. I remember tossing peanut shells over the rail. Almost 60 years later I sometimes think about that experience.

Any ideas regarding the reason the flag is at half staff? Memorial Day perhaps?

I attended many games here in the 60s. We rode a streetcar to Oakland and sat in the right field stands to get a view of Roberto Clemente. When the home team ran out at the start of an inning, we would yell, "Hey, Clemente!" He would look up and every kid was sure he was looking right at them.

Part of Forbes Field still stands, a section of the outfield wall where Bill Mazeroski's "walk-off" homerun left the stadium in 1960.

That's a 46-star American flag, which lasted only four years as the official flag of the U.S. In 1912, with the admission of Arizona and New Mexico, it was time to upgrade to a new 48-star flag.
