Maybe they were using a hollow cone nozzle.
Do you have big dogs in Leonardtown? Is there any sign of intensified green?
I'll have to check the center of the rings when I return Saturday. The customer did recently have a falling out with her Fert & Squirt company and was at one point spring dandelions as she saw them, so this is a very viable option. I'll try to get some better pictures too.
