Sunday afternoon, Mike Cole gave us a lesson in treasure hunting. Although we didn't find valuable items, we did find several reminders of our childhood. In the early 1960s, the Hanson boys got into making rockets with aluminum tubing and home made black powder. The tubing came from the TV antenna and the blackpowder was sulfur and salt petre from the Co-op and charcoal dust from hammering bits of charcoal from the wood stove.
