I want to believe it was unplanned.

While I was driving up to my adventure in The Hills Above Pacheco (song name) I drove a narrow curving single lane road full of bicyclists. I thought it might be an spontaneous biking confluence, but then I passed a middle aged woman biking in a cocktail dress. I tried to convince myself that it was not a Bay to Breakers type bike race, but then I passed a man in a purple cape.
