I worked on a dig for a month at Caesarea, Isreal, where King Herod had his palace built out into the ocean. I was in a trench up on the temple mount which had four or five religious buildings on top of it over the centuries. A Roman temple, a Byzantine church, a Crusader church. It was the people that made it exciting though. All you do is dig and dump buckets and move rocks, so it is up to you to make it fun. The group was diverse in age with three people over 70, two people 35-70, and four people under 35. We all had a good sense of humor. I invented the International signal for I’m-holding-a-bucket-would-you-turn-around-and-take-it while we stood in line to pass buckets of dirt to the dump pile. The signal involves pressing your lips together, sucking in, and pulling them apart so it makes a MOP sound. Worked really well. Better than tapping shoulders (your arms get too tired to lift that high) or using a sentence. “Hey” didn’t always get their attention. Everyone was a character, a really unique person. I think this is something worth doing at any point in your life.
