I have mowed several accounts over the years were I have found small landscape stones from the property or a surrounding properties beds that had been thrown or kicked into the grass by kids, vandels, people without brains, etc.. But, this is a new one on me. One of my accounts, I have taken care of for three years now, just had a Super Wal-mart built behind it. They put a road through next to my property. The final grade people did a crap job. I picked up 5 five gallon buckets of small to medium stones, baseball to coke can size, all in about a 20ft x 150ft space where the road cut through my account. Around the backside, Wal-mart had to put in a drainage ditch with flow stops every so often. This area is divided from my account by a 10ft wide brush area (I have put in a unsolicited bid to my account for cleanup of this area). Last week the mowing crew that mows for Wal-mart mowed this back area for the first time since they opened over three months ago. Thier side is huge, about 100ft x 300ft, excluding the 20ft wide drainage area. When I mowed my grass side of the brush area this week, I found same size stones I picked up from before, all over the lawn and even the parking lot. Upon ivestigation, I found same size stones also thrown in the brush area. I just walked this brush area a few weeks ago when putting my bid together to clean it up, and there were no rocks. Then I remembered, I had noticed all the small stones on the Wal-mart side and had thought what a mess the final grade guys made over there also. Now, I did not see the mowing crew throw those stones, but I know that they did it. I imagine they were throwing them into the brush area without really looking and many bounced out to my lawn side, which the brush is my side also. I picked up three 5 gallon pails in the grass and parking lot alone just to be able to mow. I wanted to just throw them back over, but I am not that kind of person, besides they might throw them back again. That could go on for ever, besides they really do not care about thier expensive blades, they are just lawn grunts. Any ideas?
