Who has the laser?
Probably the Cal-Poly folks. They usually have the neatest stuff. In the Rose Parade I saw they had a bunch of sign carrying supports streetside across from the TV anchors. 'Their' float hosed them with hidden water fire extinguishers! The networks, at least the one I'd taped, missed it but we caught it on our own video. Alas their float will be out of range, blocks ahead of Occupy.
