Suzles, was your group protesting on McKnight near the south end of the airport a few of months ago? I remember driving through there wondering what was going on, but barely made out something about horses, but nothing else. If so, I'd recommend bigger signs. I honestly drove though there thinking it was a strike of some kind, but a little farther from the postal sorting facility than normal.
I admire your dedication to something that is close to your heart. Just a friendly suggestion.
