Some of the best sights included a gigantic dragon posing for selfies, a photo station made from a Volkswagon "hippie bus" staffed with a couple of "hippie chicks" from the 60s, and a little girl dressed as a policewoman who was delighted to meet up with an actual policeman (it was mutual).
I didn't make a costume this year (again!), but I enjoyed walking around a bit and just sightseeing.
Before that, though, I thought I'd do a very Halloween-y thing and watch the bats come out. Our little pocket park with its two bat houses sits only a block away from all the festivities. Surprisingly, I was the only person who thought to do this.
Maybe next year I should host a watch party!
