Los Angeles is so diverse, that sometimes it's hard to tell the tourists from the transplants. Even Asian and Latin American immigrants blend in better than some of the gringo tourists and transplants. Sometimes it depends on the time of year, but some gringo tourists stick out because they're very pale, and/or wear shorts and t-shirts in 50-degree weather.
Seattle folk and umbrellas? Well in LA, you see Asians carrying umbrellas in the summer for shade, males and females. Some white folk have taken to doing it too. Makes sense to me.
And then some tourists you know just have to be from another country, like these guys; I took this picture in September 2019, riding the Metro home from Santa Monica:
My partner and I were all "So what country do you think they're from?" We weren't sure; we couldn't hear what they were speaking. But judging by the odd white tennis shoes, the bad haircut on the one, their body shapes, and the man-purses, we just knew they weren't from the US, let alone LA.
