I did check the local papers and couldn't find anything. My memory is foggy on the date, but I DO remember that it happened. It was either on a Fri. or Sat. evening...

I'll keep checking.

Apparently this has happened in the distant past.:

A manhole cover turned into a missile and killed one person after a subterranean explosion in Chicago in 1937.

Powerful Bomb Explodes In Volusia County Park
POSTED: 11:52 am EDT July 26, 2004

HOLLY HILL, Fla. -- A powerful bomb exploded in a Holly Hill park. Now investigators are on the scene to try to figure out what the bomb was made of and who set it off.

The bomb was in a trashcan there. Investigators say, this was no ordinary pipe bomb.

"This is not a chemical bomb that some kids did. This is a major explosion," an investigator told Channel 9.
