A few months ago, I shot a Ninja Camp upstate. Aside from your typical archery, knife, and hand combat training, camp attendees get trained in environment awareness: playing a game where some of the camp's members are dressed and acting like common citizens, except there are minute and subtle details that the other camp members are required to make note of. This can be anywhere from a suspicious person with a gun, a lone backpack, or a houseless man with an expensive watch on.
