Seems like it would have been easier to have a "forward only" sign, instead of this mess... well observed with a great title! The signs seem a bit gray - in Photoshop (or what have you), you can make the whites of the signs be truely white by using Levels, and it would have made the photo brighter & not so murky.
Great signs but its not the clearest shot I've seen. I find there's a lot of noise in the shot but it is level which I find a lot of photos in this challenge aren't. Good luck in this challenge.
