Blank Sign

I passed a church the other day that had a sign that can be changed each week to make an announcement or display some cute message like, "What is missing in CH -- RH... U R". However, in this particular case the sign was blank. I couldn't help but think this sign was screaming, "Keep driving... nothing going on here". To make matters worse, this was the church that my family had recently left after attending for over 7 years. If you passed a church with a blank sign out front, what would the sign be saying to you?
