It turns out they printed my three photos in the paper! Yay! They also said that a group went and sprayed Round-Up on August 16th. They must have sprayed only one area, because my Aunt Mary's section has a few stones with weeds taller than me!
I have another trick up my sleeve which I will implement next month. I'll let you know if it keeps the weeds out. It's going to remain secret for now :)
