Me and the guys mowed a couple truck stops this summer.
Hideous landscaping, some of it still "natural".
Rough is a strong understatement. Were it even a little bit smoother we could have cut quite a bit of time off of the amount of time needed to mow it.
Professionals are people who can do their job when they don't feel like it.
Amateurs are people that can't do their job even when they do feel like it.
