The Macadam Bay wigwag is my most viewed. It's been up since October '06 and has had 23,471 hits despite the poor quality. I plan to eventually re-shoot this one and get the Riverwood Road wig' in action.
This was from a fire alarm at my college. The biggest comments I got were people asking what happened and people's amazement that the alarm signals were bells, since the use of bells in the majority of the US is pretty insignificant, usually favored instead for horn/strobes. I grew up around bells all my life, and thus, I have a strong liking for them.
