Demonstration today – AZ 51 and Highland overpass in Phoenix, AZ.

From the event’s Meetup page:

    Many of you have asked for and suggested a sign wave demonstration in central Phoenix and more specifically on Highway 51- home of those nasty fixed units that are strategically positioned for Southbound drivers.

    Well- your answer is here!

    Announcing the latest signwave – 51 & Highland, right in the heart of 51’s lineup of scam-cams.
