Lacking a GoPro, I used a GorillaPod to attach my tiny Canon point-and-shoot camera to my bike’s handlebars. The Canon doesn’t really focus anymore (and little else works on it), but it does capture video of a sort.
With the Canon point-and-shoot on my handlebars, I rode my bike to the Siantar Zoo and wandered around for a bit. I’d been to this zoo before and taken a lot of pictures, so I didn’t spend a lot of time there on this second trip. I played around with my Olympus and a short telephoto lens and shot some short video clips of the various animals and then rode back to my hotel.
