1) What dummy head did you get, and roughly how much was it? What kind of mics in it?
I have always meant to get around to doing binaural recording, myself. There's a few spots near me where the sound is just unbelievable, and I'd love to record them.
2) There's a podcast of people who go on the rides at Disney parks and record them in binaural. Some of the recordings are good. Some are, well, interesting.
