that ride is close to where my office was in san diego. one of my favorite after-work rides. i rarely saw other bikers on it. first time i rode it was on my 4 inch full susp (many years ago), then on my 6 inch, then on my 8 inch travel bike...all 26ers.
now that i have a 29er hardtail i'd like to try that trail again if i'm ever down in socal.
Where's the sweet videos going back up again?! Just kidding. Sweet looking riding spot. I'd give you even more props for riding it rigid, but I don't know if that bike counts as a "rigid bike." Nice to see those wheels working over the rocks, speaking of which they looked to be working really well when you got some speed through some of those sections.
