Hello, well I guess my sister wants me to blog!! I have NO IDEA what this is. I am going outside to spray poison on all my weeds that are taking over the entire yard. I tried the back to nature approach, like vinegar, pulling weeds, (OUCH) etc etc. I am going to kill everything that grows, put gravel and brick in the back yard and make a patio where I can relax on my days off and not get overwhelmed with the jungle that is growing!!
