San Diego Happy Hour, PDDs & Cities + Travis K Before we get to some big news about PDDs (or as normal people call them, "delivery bots") - we want to remind everyone to join us on Friday in San Diego for our Mini Mobility Happy Hour. In true SD fashion, this meetup will be on the chiller side of the spectrum, so please drop on by Stone Brewing at Liberty Station from 5:30 to 7:30 to chat about all things mobility, delivery, and more.
