Concentration showing as Kathleen crosses a bridge over Buffalo Bayou. These wooden bridges are known to get very slippery in the mornings. I experienced significant schadenfreude a while ago when a biker barged by me from behind right before a bridge, slipped and then crashed unceremoniously. He was ok, just embarrassed as hell.
Like so many runners, there's never a good pic taken of me while running, always making weird faces, gasping or otherwise contorting the mug.
