This one is just for fun as it isn’t a nature shot. It does fit the description of the challenge though. I was hiking with the dogs on the river flats and was taking photos as they chased each other. This shot, by pure chance happened to catch them in the middle of identical strides despite their size difference. I could have tried all year to get a shot like this intentionally and never would have accomplished it!
