I never got the chasecam working, so I have no video. I fiddled with for a while when we stopped at the dam before heading up the mountain.
When I got home, I tested the cam to see if I could figure out what was wrong with it, and the damn thing worked! IDK what was wrong earlier, though.
I'm thinking about making a mount that will clamp on the posts of the headrest and hold a camera in between the seats. I've got some ideas about how I could do it on the cheap, so we'll see what happens.
