Surely he filmed this for a video part or something.
This guy has been on a tear throughout the bay area. Every instagram post is some next-level hill bomb trick.
I haven't met him, but I get the feeling that he just moved here and hasn't taken a really good hill slam yet. This is actually a phenomenon I have observed - people move to SF and get fearless bombing hills until they take a spill. Some chill out after, and some do not.
Edit: and as a side note, I don't think these tricks are being filmed for a video part. He has a steady stream coming out of IG. Sort of a shame as he could film some next-level part.
