Here's the billboard ad that went up near downtown Dallas, TX. It's at the corner of I30 and Peak St. Unfortunately it's a part of an ad rotation schedule on a digital board with 4 other ads. It get's shown for 5 seconds every 30 seconds.
I30 is one of the busier freeways and get's bogged down during morning, noon, and evening rush hours, so there's plenty of time for drivers to see it and absorb the message. :)
