Why Were All Those Fire Trucks at Busch Stadium Yesterday?

If you happened to pass by Busch Stadium early yesterday morning, you might have thought the ballpark was burning to the ground.

By 8:40 a.m. at least a dozen fire trucks and rescue vehicles -- their lights flashing -- idled on a blocked-off section of 7th Street, just west of the stadium.  

So, what was the occasion? A three-alarm fire? A terrorist plot? Disaster training? Nope. Yesterday was "Picture Day," with the department lining up all its newest equipment for inclusion into the memory books.
