This picture doesn't do it justice

In June 2010, over the edge of the Hoover Dam.

I'm not particularly afraid of heights, but this activity made me a little uneasy.  It was a very, very, very long way down and the guard railing thingie comes up to about your waist at some points.  It didn't help that it was windy that day, either, though I suspect it's always gusty up there.

Shudder.
