Daily Postcard: A week-old mule deer fawn’s energetic ‘workout session’ is captured on a game camera Friday at a residence on North Mesa. The fawn’s mom apparently selected this backyard as a safe location for her baby to make multiple circular full speed runs around her until it was out of breath. Nature employs this procedure to build up a fawn’s endurance so it can run long enough distances to escape a pursuing predator. Photo by John N Dragon
