Sometimes, inclement weather can work to your advantage when you're out railfanning. For one thing, you won't need your "other railfan filter" as much since there'll be fewer railfans out in the weather with you. Also, you'll be able to get those really dramatic shots that just don't happen on what I call "Kodak clouds" days. This photo of Wisconsin & Southern 4025 was taken during a rainstorm in 2005.
