They just demolished the Capital Center, also known as the US Air Arena. It was an ugly building, and the new downtown arena in DC is in a much better location. But the Cap Center was part of growing up in Prince George's County. It is where I went to my first rock concert and where I graduated from high school. And I remember going there with my family a number of times to see "Spirit of America" pageants put on by local military units, and one time I was part of a chorus that sang the National Anthem before a hockey game.
The arena was built in the early 1970s, and I grew up along with it. It was probably of limited use with no hockey or basketball team to fill the seats. But it's still sad to see it go. They're going to build a shopping mall on the site.
