I have submitted 2 photos to "Insanity of Humanity," and none towards "Metal", so it can't be THAT hard. To me, "Insanity of Humanity" refers to humanity's need to do senseless things that put their lives in danger, or just make no sense whatsoever. What feeling of accomplishment is there for some of the things we do.
My submission had a pair of shoes dangling from power lines. Why? Why would someone spend so much time doing that? It's a hard thing to do.
My 2nd photo for this assignment is below, also for "Insanity of Humanity." Hey, everyone else is doing it!

Not as sharp as I'd like (at all), but it was taken with only my 18-55 mm Nikkor kit lens with me, and these guys were moving
FAAAAAST. I manually focused the entire time since they were always moving closer and farther away from me. It was the 1st time I absolutely had to manual focus. Very difficult. I couldn't tell whether he was in focus or not quickly enough. 130 shots of these guys, and around 10 of them ended up this good, and it isn't even "great."

Everything ended up really blurry and dark at 55mm, so I was forced to use my lense between 18-30 mm just so I could shoot at f/3.5-4.5 rather than at f/5.6. A little bit of light goes a long way when they're moving this fast.
It was a crazy display, especially when they fell off.

I wish I had a faster mid-range or telephoto lens with me. The size of the "bowl" (don't know what it's called) was very deep, so sometimes they were close, and sometimes they were far away. They moved up and down that bowl-thingy, so I just waited til he got close.
