I did my first (and only so far) SJBP about three months ago. I had a good time, but the hooligans were really, really annoying... and it was mostly guys on fixties in front of me who were weaving and threatening to clip my front wheel. I finally raced to the front of the pack and had a much better time away from the bulk of the crowd.
I'm looking more forward to the
Tweed Ride again, but I have to make some spiffy duds first!
