When anyone mentions lifting stone and gardening in the same breath, I flash back to the time when there was some leftover bank run type of stone piled on the lawn near the end of one of my driveways after some repairs at road edge, and I thought to move the stones back to a spot near my barn and just rake the silty part of the material into the driveway and the lawn, as it would settle with a rain. I fancied the stones themselves would be perfect for drainage at the bottom of large crockery I liked to use for geraniums put here and there around the place in summer.
Well I began picking the stone into a five-gallon bucket and when it got like half full I'd pop it into my garden cart and wheel it back to where I wanted it. The afternoon wore on and I was about done. but there were maybe two of my desired-weight loads left. I was tired of the whole project really, and it was so tempting to just get it over with already.
So I piled half of what there was into the bucket as usual, and then looked and figured well what the hell. I can fit the rest in there, and it's not like I actually have to carry it, just pick it up stick it on the cart. One and done, instead of two trips! So I recklessly piled the whole lot of what was left in there and then gave the bucket a massive pickup effort... almost dislocated my shoulder! I could feel something almost ripping in there...
Huh, okay... so I set it down of course and unloaded more than half of it and picked that up with the other hand, toted the cart back and then stashed that in the barn and called it a day. Next day went out and got that last batch of rocks, still using the other hand, because I could feel that shoulder suggesting "go ahead, I dare ya".
I didn't so much as pick up a bag of flour or cat litter with that arm for about a month. Never tried to rush a job like that again after such a close call. And yeah my back was tired too from using a garden cart instead of a wheelbarrow. Haste makes waste! The barrow was in the back of the barn and I was too lazy to go an extra 20 feet to fetch it when the cart was right there by the door...
