I got the chance to ride up a local ski hill so I shot a few videos. I should have run a helmet mount, the view for the chest mount is too low and very shaky. It turns out ski hills are pretty bumpy when not covered in snow.
Chasing a Stella with a p200 motor and knobby tires up a side hill. I was going hard on this run, had a big slide at 16 seconds in. Sadly the camera makes it look kind of slow. https://www.youtube.com/watch?v=wIe5y2XtWF8
It was a blast. It rained a few hours later, just enough to make everything damp. Another guy went up on knobbies and several people said it wouldn't be possible on street tires. I didn't agree so I made a few more runs and those were even better. I was sliding all over the place. But I did make it up all the trails.
