After a strong ride with a weekly group, Janet and David Merriman pedaled home, with a detour to check on a friend’s house they were watching. As dusk gathered, they turned left on 16th, east of Sullivan in the Valley, taking it easy after the 25-mile run out of Wheel Sport East. They saw deer grazing off to the right as a car approached. Suddenly a fawn darted from the left into the path of the car.
