Lt. Col. James DeHaan, 436th Airlift Wing chief of safety, hands out a stop sign-shaped designated driver key chain Sept. 1, 2011, at the Dover Air Force Base, Del., main gate exit. The wing safety office handed out key chains and pens as Team Dover members left for the four-day Labor Day weekend, reminding people to have a designated driver if they plan on drinking.
