Guy on a job in Akron showed me his trick for digging post holes in clay soil
I was working a fence line last summer in Akron, Ohio, and the ground was just terrible. Pure red clay, hard as a rock after a dry spell. I was sweating bullets trying to get these holes dug, my auger was barely making it 6 inches down. Then this older fella, maybe 70 years old, walks over from the house next door. He says "you gotta soak that clay overnight first, then dig in the morning when it's soft." I thought he was blowing smoke, but I was desperate so I tried it. Next day I was able to get 30 inch holes no problem. Has anyone else run into that trick with stubborn soil? Worked way better than I expected.
