You can now take a trip down sections of the Colorado River Ala Streetview. This took a few more years than I anticipated. When in whitewater, the camera system does an admirable job of staying in relative position, but it's not perfect. Wide swaths of image artifacts are prominent at the raft level.
There's room for improvement, but it's nice to see the effort to show the public some of the experiences river runners enjoy.
