First night of summer, last day of school, whatever the case, a little edgy down along Alki Beach just after sunset — we were out for a simple “scenic drive” en route home from downtown, but things bottlenecked right around the Pepperdock — at least half a dozen police cars blocking off a side street, officers walking warily around the edge of a fairly thick crowd on the beach side of the street. Hard to tell if any actual trouble had brewed, but with the crowd so close to the traffic lanes, we felt a bit nervous. I know Alki’s been a gathering place for The Young Folks since the dawn of time, but this density seemed a little unfamiliar.
