At the NECCC conference, one shooting event they offered was to photograph some BMX riders doing tricks.  It was a difficult place to shoot for clean backgrounds because all of the college buildings were in the background, but I was able to get down low and get some shots of the riders against the sky.

After the all the jumps and tricks, they brought out the models so we could shoot them with the riders.  I was able to get some portraits and some images with action.
