You can get there from here.

I love random reading. First correct answer gets some sort of prize. Maybe an entry with their name in big letters or something cheesy. Anyway, the challenge and desire to find out something random should be enough. Right? Right?

When the American flag is flown by suspending it overhead, there are several rules governing its posture. One is that the union should be at the top. However, the usual rules about flying it on its own right are a matter of perspective. How should the flag be oriented:
a) in a hallway or corridor or above a street?
b) above an intersection?
c) in an open field with no defined flow of traffic?

Suggested tags: "capture the flag." Be glad that I chose hallway, intersection, and field as my descriptors. I really wanted to express them by their symmetry groups C₂, C₄, and C_(infinity).
