Careful how you mark control locations in urban orienteering events!

Obviously some form of terrorist activity. Everyone knows no self-respecting Canadian would take a selfie with a Coors Light logo in it.
Plus 2 JayXC! But it doesn't just apply to Canadians, eh?
Count 1: self respecting hominids don't drink Coors Light.
Count 2: self respecting hominids don't take selfies.
This is way more publicity than orienteering ever gets, so maybe it's worth a shot.
(Somewhat related: when Cascade just hosted a race on a university campus, we sent photos of controls, SI units, and runners punching controls to the campus police so that they knew what our stuff was in case it became an issue on event day.)
We actually had a phone conference with SFPD before the very first Street Scramble (not counting Night & Day) in San Francisco. Stupid people worry about permits, insurance, and safety; smart people just have a big bank account to back them up, and they can do whatever they want.
