Had 6 or 7 yards when I was 12 years old, with only a push mower and a can of gas and occasionally the dreaded "weedeater " which was a large pair of heavy metal sheers to do the fences (horrible).
I always had money in my pocket and had to join my buddies on Saturday afternoon afterI did my yards. Learned as much about people(aka the public) as anything.
Our teaching the work ethic to young people is vastly undervalued IMO, and as the cheap labor kinda takes a step back, could be really beneficial. There's plenty of money to be made in the trades if an American guy doesn't mind sweat and getting dirty.
I don't think you know me.
