It was kind of funny. Joshua's not quite big enough to master the mower. He wasn't sitting back far enough, so John was having to hold the seat down to keep the mower from dying.
He finally got it down. Luckily, he is my more cautious child, so he didn't even try to go very fast. He did have a lot of fun. And to be fair, John didn't have the mower blades engaged, so it probably wasn't even too dangerous.
