The boy/teen I have mow my lawn every other week is now 17...he's done it faithfully for the last 5 years.
He's told me he'll continue to do it, at least until he finishes high school.
Lucky you! But your lawn care kid is 17 - you'll see what it's like to find another in the next year.
I used to hire teens for lawn care and snow shoveling. They won't do it anymore. I'd hire a teen in a nanosecond. But now I have to hire services, and they send out Hispanics. Do I know if they are legal? No, but they do a good job, and I don't have an alternative.
