I noticed these signs around Walnut Creek “celebrating 100 years” aka the Walnut Creek Centennial. I think they look great but the back side is empty so when you’re leaving Walnut Creek going onto Highway 24 you’re greeted with a giant empty purple sign. I think a message on the back would have been a nice touch. Something like, “thanks for stopping by” or “you’re leaving Walnut Creek”. Any other suggestions for a backside message?
