Doesn't sound like it's the best location for a bomb disposal site?

"The cantaloupe-sized cannonball missed the water, tore through a cinder-block wall, skipped off a hillside and flew some 700 yards east, right into the Tassajara Creek neighborhood, where children were returning home from school at 4:15 p.m., authorities said.

There, the 6-inch projectile bounced in front of a home on quiet Cassata Place, ripped through the front door, raced up the stairs and blasted through a bedroom, where a man, woman and child slept through it all - only awakening because of plaster dust.

The ball wasn't done bouncing.

It exited the house, leaving a perfectly round hole in the stucco, crossed six-lane Tassajara Road, took out several tiles from the roof of a home on Bellevue Circle and finally slammed into the Gill family's beige Toyota Sienna minivan in a driveway on Springvale Drive."
