Big Road Sign

Apparently today was the day it became illegal to text while driving in Pennsylvania.  I know this because as I was driving up US-202 there was a notice on one of those billboard-sized lighted signs.  It read something to the effect, 'Texting while driving is illegal.  Keep your eyes on the road."  That's just great.  A huge lighted sign off to the side of the highway begging to be read, and then the message "Keep your eyes on the road".  I pulled my car back into the correct lane and thought about the irony.
