May of 2015 I woke up early to 6 inchs of snow in Yellowstone Park. I went straight to my car and started driving thru the park. I was the only vehicle on the road and it was beautiful. I happened along a female bear and her cub and did not have to worry about crowds or traffic. Best day of my 5 days there. f/13, ISO 200, 1/1250 sec. hand held.
