We've all been there. You hike up to a spot, sometimes in snow up to your waist and check the angles with your camera. ERROR NO CARD. So you run back to the vehicle, thanking the lord you have backup cards. Normally this wouldn't be as big of a deal, as you could hear and see the train coming well in advance. With a blizzard howling, now its just up to luck. Arriving just in time, standard cab EMD's from a dying railroad thunder up the mountain, making all the effort worth it.
