Rode 20 miles to get there, and the ride was somewhere around that distance as well, mostly uphill.
I have no idea what the audio is, mine doesn't work. There were quite a few fixed/ss riders. I think 50-60 people showed up. Just thought I'd share.
p.s. At like 9:05 you can see my blue-ish headlight, then at precisely 9:17 you can see when I eat **** running into someones rear tire trying to avoid the merry-go-round stoplight nonsense. Then you see me at 9:35 on the side of the road fixing my handlebars. Good times.
