Man I have been cutting grass since I was a kid, Dad had a push mower, Grandpa had a self propelled mower, both their yards had hills and I cut them both until graduation. I guess the Army gave me a 4 year break from cutting grass. Then home ownership and I have been cutting ever since, I do have a riding mower for my own yard.
I wish there were some ambitious kids in my area, not that I don't want to cut my own lawn more a life lesson for them on how to make a buck. I don't really think I would pay a service to cut my grass, but if any younger generation looking to make some money I would pay them to do it.
