This one comes as no surprise since working outside is a well-established dad pasttime.
And yes, there might be some truth to the rumor that dads like mowing the lawn because it allows them to buy a riding mower which leads to delusions of grandeur involving their ability as a NASCAR driver. But the main reason this job made the Dads Top 10 is because groundskeeping is important to their families.
Not only does this job involve mowing the lawn, raking up leaves and gardening, but a groundskeeper is generally responsible for other things like snow removal. Keeping stairs and walkways free of debris isn't just an issue of aesthetics, it's something that prevents injuries and literally keeps their family members safe. Which is why dads consistently brave the hot sun and icy winter conditions to make sure their spouses and children are taken care of.
