I have some sound files from my roadtrip this summer I'm only now posting. These are from Glacier National Park in Montana, and one from Cedar Breaks in Utah. My iPhone can't capture video but recorded soundfiles of water and wind and footsteps. There's something that I actually like more about having sound and discrete stills; somehow it captures my memory of the experience more closely.
