Thanks Madman. My intent is to make an audio recording of the same stretch of brook (or really, any brook) and use that instead of music. We'll see, though, whether intent translates into action....
If by "awesome flying" you mean my close proximity flying to the branch at about 50sec in, truth be told I didn't see that branch until I was going over the footage on my computer.... Got lucky!! Moral of the story is that I now pack a pair of compact binoculars in my kit to better scope out similar flying situations.
