After chasing CP 299 with a SOO SD60 leading, 281 showed up with two SOO SD60s! Unfortunately, every shot opportunity for 40 miles was ruined by clouds until this last bit of light was found before the sun went down. After such a long chase, I have to wonder why I can't give up on getting a photo no matter how many miles it takes? Although not a great composition, I think the light makes this image worth the effort.
