Today I have my dream job working at a powersports dealership [selling quad bikes, jet skis and snowmobiles].

现在我拥有了梦想的工作——在一家动力户外零售店（售卖四轮摩托车、喷气艇、雪上汽车）里。

Apparently there are men with clipboards keeping track of the planes circling the airport and men on quad bikes guiding the aircraft into the limited parking space once they land.

显然有人拿着手写板，密切追踪在机场上空盘旋的飞机。还有人骑着四轮摩托车指引降落的飞机进入空间有限的停机坪。
