I hate those days when you realize you have grown your beard just beyond what a standard 5 blade razor can handle. You need something else. So you dig deep and find your hair clippers to start the job, then move over to the straight blade. There are others who go even further and start with sissors, then the clippers, then the blade.
This is what happened with my lawn. I let it go too far. I now realize why people mow their lawn more than once every 2 months. July and August just slipped away from me. Below is the evidence. I also used the excuse that I was growing it out to let it get thick and healthy. Although it seemed green on the top, below it was a damp yellowish mess.
