Explain this please - Does this involve actual controls, streamers, or answer questions? Is a permit required or is it just discreet as there are so many other people running about?
OCAD map, quite well done and Honor system that involved locating a certain object at each control. All were easy to find with no angst on deciding if it was 301 or 302 steps to the top of the Lincoln.
Only Rules were to obey street crossings and not to run down tourists. No permit, and with the whole Pokemon thing, I don't think we looked out of place. The bigger issue was the clueless people on the rental bikes, disrespecting the monuments, riding on sidewalks among the throngs, and such.
It was good fun, and I saw more of DC in 90 minutes, plus the bike part, than I have seen in 30 years all together.
