It was quite warm this morning at 6AM, 50F & dry with no wind. Ride in was uneventful until I was cruising through our empty parking lot. It was very dark & my vistalight illuminates a very small circle. Our building has numerous 18"X18"X6' cement barriers all along the building between the walk way & parking lot (this was done after an irate citizen made our Yakima office into a drive through). The local skateboarders had dragged one of these barriers out into the traffic aisle & as I entered it was edge on & unseen by me. Missed it by that much! as Maxwell Smart used to say. We now have all the barriers anchored with L shaped steel straps. See how long it takes the kids to defeat these. Don
