It was a concert. I went with one of my friends to go see Nickelback, who had My Darkest Day, Seether, and Bush for lead-up. None of these bands disappoint in concert, and I would happily go see any of them individually again. It was definitely one of the best experiences of my life.
It was the Memorial Day Parade in Washington DC, back in 2010. It was epic! Watched some of the prep, there was a guy on bagpipes practicing, and and he broke out the Star Wars, which you would think sounded weird coming from that instrument, but it totally didn't. Plus there was a Delorean. It rounded out my nerd points of the day.
After seeing Jet Li in "Romeo Must Die", I wanted to go back and see some of his other performances. I liked this one a lot. It's called "The Black Mask". English subtitles are available for the movie, since I think like CTHD, it's in Mandarin. I see it as if the Green Hornet meets Batman, but GH is Cato. Very cool to watch, and see Li in action is always a treat.
