A little update. One of my customers contacted me via email and wanted both her properties mowed today. On her residence, it had been 3 weeks, but only one week on the business, which surprised me. I checked all my other accounts here in town, and actually ended up mowing 4 others as well. They could probably have all been stretched into next week, but they all looked better after mowing. All had gone 2 weeks or more since the last mowing.
