Near and dear to my heart is signage, well good signage I should say. Unfortunately we are surround by lots of bad signage.
As I have mentioned before, Millbrae Station does not have very good signage to tell you which operator is located where (BART, Caltrain, Samtrans). I challenge you to see a sign at this entrance to the station (besides the one on the train which will be leaving shortly). At a minimum there needs to be a sign that includes all three operators logos.
I am going to write more on this later, but I just read a good article that talks about this very issue and the great progress that is being made.
