@edgarblythe,
Looking back on it, I can't believe they had us doing it.
Of course, we did all sorts of crazy things as kids; on bicycles, in trees, and scampering around on the roof of the big old schoolhouse catching pigeons in gunny sacks. Rolling down hilly streets curled up inside of truck tires was a good one, too.
Thinking back on it all, I'm amazed I'm here to tell of it.
