We live at 4881 Leonard Road. Today 3/13/18 we came home to our mail box and got our mail. By chance, I looked over (about 25 feet) to my right and saw a clear plastic bag hanging on a fence gate that is-not used. I investigated, and found a box inside the bag addressed to us (UPS GROUND # 1Z 695 855 03 0470 6781 , From: Valley Vet Supply "pet medication") tied to the not-used gate. Thankfully, I happened to spot it. This is the second time in less than 6 months this this has happened. By some chance, If our mail person is doing this, please have them stop this practice. Please deliver any packages that don't go in the mail box, to right- in-front of our home front door under the overhang. Thank You, Liz Vannata P.S. If you have any questions you can contact [number removed]
