Then there wass the time a friend and I spent and hour and a half after school looking down a storm drain ("sewer"). Finally my grandmother called the convent to see if they knew where I was -- one of the nuns came over and asked me if I was me, I said yes, and she took both of us over and gave us a cookie while they called the responsible parties to come collect us.

Just an early example of my life-long interest in sewers.
