I met my brother after work for a quick out-and-back on the always fun Desert Classic trail at South Mountain Park. We started late and finished in the dark with lights. Either my light batteries aren't holding a charge, aren't recharging to 100%, or my night vision is deteriorating in my old age because like last night, I was having difficulty seeing details of the trail. So I rode slow which was fine as my legs were tired anyway. The picture above was taken at the point we turned around to start the ride back to the cars.
