Smart Burrs

We're all familiar with smart phones and smart TV's and smart this and smart that. Well have you ever seen smart grass burrs, my take on them? I don't have any idea where all grass burrs grow, but we have more then our share here is south Texas and a good portion of them are in my yard. I've fought them, I've hoed them, I've pulled them by the roots, I've sprayed them with weed killer and nothing gets rid of them. So I resorted to letting my neighbor mow my yard every time he mows his and that is often. Of course I pay him but I came to the conclusion mowing them was keeping the burrs from growing tall and being tracked into the house. Ever step on one in the middle of the night walking on the carpet? Ever try to pull one out of a piece of clothing when it was washed and dryed in it? All I can say it is one big "OUCH". It worked for a while with the neighbor keeping the grass mowed short and keeping the burrs from growing tall until the grass burrs got smart. Now the plant spreads out and hugs the lawn so the mower slides right over the grass burrs mowing the grass and leaving the grass burr plant to make those hurting burrs for me to step on and bring into the house and on to the carpet. Thus---SMART BURRS.
