I just took my first spin on mowing the back yard, which is just under an acre. I used the riding lawn mower (the first time I've used such equipment), and after a few learning hiccups everything fell in to place.
With the pretty sunset and pleasant breeze (and noise canceling headphones) it was actually quite a pleasant activity.
It was kinda like doing one of those Zen sand garden thingies. But louder. And with gasoline.
And with little bits of grass going up your nose and in your eyes.
Can't wait to do it again.
