Thanks Steamboat! Will share a story with you, true story! Millions wouldn't believe, but maybe you will...
Was out front of the Big Ball talking for quite a bit with the PP Photog out there between the fountain and the big main planter, and I see the Tron-o-rail go by behind her and call out, "Tron-o-rail!" and whip up my camera and grab the shot.
She looks and turns back to me and says, "The yellow one: you know, there's a blue one too!"
