I use to be a machine operator making peoples yards look good with a bobcat and hand tools. This sometimes took some creative thinking on how you are going to make this yard flow from the curb to the back fence; it all has to look nice. In some yards that I have done you need to think on the spot and make the decision on how you are going to make it look as good as you can. Some people are really picky when it comes to how their yard looks. One customer we had, spent over a hundred thousand dollars just on his yard! I worked on the top soil for his yard for two days and he made me go over it until it was as flat as a pool table. The other workers and I took our time and got the job done with a very happy customer in the end. The purpose of teaching this in school is to let you know there is more than one way of doing things. Sometimes you have to think outside of the box to get a job or task done
