I have a groundskeeper. His name is Jeremy, and he does a much better job than I could in my decrepit state. He does stuff in ways that I think are wrong, but I bite my tongue. I'd much rather him do things wrong than me do them right. And I'm one of his best customers, maybe his very best one.
Each week I chase him down the road waving money at him. I pay him every time with a smile. He also does a good job of trimming, maybe just short of spectacular. The last few days the temps were up almost to 90, but Jeremy just cuts and trims away. Keeps me happy.
Down the road a bit the stupid city brought in goats. I was kind of afraid they'd be attracting ISIS fighters, some being female goats. None yet.
I'm going to guess one of the most peaceful sounds is a mower cutting your lawn while you nap in your recliner. What also makes me smile is hearing the neighbors mower whilst I'm sleeping. I can almost hear those fools sweating.
Now lets not confuse mowing with snowblowing. The blower is one of the best power tools ever. Like so many things it can be used for good or evil. I prefer the evil uses. I pretty much detested my former neighbor, Roy. He was a piece of work if I ever saw one. Didn't work, nor did he partake in any form of yard work. He had free rent, and one rule of life was not to move away from it. He didn't move willingly, but the state took him away back in July of 2005. Its been pretty much vacant ever since. Hard to do evil in the summer, easy in the winter.
One winter he had his van crash landed out front. Usually I'd clear the snow all the way down to the widow womans house, but I'd drag the blower over his walk. Then one day I decided I'd give in to my wife and other neighbors complaints that I should do his, too. So I did, blowing all the snow under his van. That made it pretty much immobile for the rest of the winter.

When they finally just had to move it, it took them hours to shovel it out. And the beauty of a snow blower is the stuff kind of behaves as a liquid until it stops moving. It then turns into a solid. Like ice, with a nice smooth top just like Gawd put it there Himself. I can't think of any other evil where it comes out looking innocent.
