As you can imagine, this creates a tricky situation safety-wise. How do you get rid of old dynamite in a nitro-stained wooden box? You sure don't haul it to the town dump.
Our solution was for Dick and I to gingerly lift the box and carry it down to the woods in the river-bottom behind the house. Then Dick got his .22/250 varmint rifle with the telescopic sight, assumed the prone firing position on top of the hill, aimed at the box, and fired.
The result was tremendous blast that reverberated up and down the Paw Paw River Valley, and, as we later learned, scared the hell out of the people in the house nearest across the river.
Obviously, we didn't publicize the incident.
