The city is replacing old, ALL CAPS street signs with new signs that use a mix of upper and lower case, under the auspice that the new-style signs are more legible. Be that as it may, they aren’t as attractive.
You’re going to have plenty of time to contrast both styles, though: the city decided last year to only replace the street signs as they wore out, leaving a mix of old and new for years to come.
I definitely prefer the all caps to the others. They stand out more that way and feel more "important". Change is good!
OH COME ON! Are you serious?
All caps is much easier to read, and also means they never make a mistake and forget to capitalize something like the K in DeKalb…
