We met at a contra dance in Berkeley, but we can't remember exactly when - fall 2013?, when Yoyo was working at Google, living in San Francisco, and Becca was starting her PhD at Berkeley. Many years passed with furtive glances, but nothing came of it, until one of us (we forgot who) invited the other to go on a foraging walk in Codornices Park. Some other memorable early dates include backpacking in the Mendocino National Forest and hiking to see wildflowers on Ring Mountain in Marin. We did more activities together - rock climbing, cooking, dancing, running - and Becca convinced Yoyo to train together for the Monterey half marathon. On one of the training runs, Becca was shaken to learn that Yoyo had never read any Harry Potter books. In spite of that, their love continued to grow. The rest is history!
