Sorta random... About a year and a half ago, I was with a customer, and as he looked at the clippings [from his lawn] that were dumped in his yard waste can, he said to me "man, you can tell how good the quality of the lawn is just by looking at these clippings. That's definitely some healthy grass! Just look how consistently green that is!"
The guy was kinda weird, but that really got me looking at not just my finished product, but also what's been cut from it. Sometimes the proof is in the catcher. Clean and green: )
