I saw quite a few Flash T-shirts in San Diego this year (more than I’m used to seeing at Comic-Con, actually), but only two people dressed as the Flash. Interestingly, both were women.
While all four of the major Flashes have been men, DC has published a number of female speedsters, including several alternate-reality Flashes and two who have worn the Flash symbol in-continuity: Lady Flash and Jesse Quick.
I also found it interesting that both costume designs incorporated sunglasses, reminiscent of one of Jesse’s later costumes and of the Kingdom Come version of Iris West II.
Update August 3: Wallyoeste and West both pointed out CBR’s 3rd Photo Parade, which includes two pictures of a couple in Flash costumes. Part 4 has a picture of a DC group with a fifth. This brings it up to at least 5 Flashes at the convention: 3 women and 2 men.
Update 16 years later: the CBR photo galleries are long gone, and the Wayback Machine didn’t catch any of the images, so I’ve removed the links. But I still have that Nightmare Before Christmas T-shirt!


Since I was going to the
When I walked by the first time, I only noticed the line running to that corner you can see at the end, maybe 3 storefronts down. About 10 minutes later, after stopping at Kelly’s Coffee, I saw that they were wrapped around that corner, almost the entire length of Forever 21, and stopped at the edge of the patio for the restaurant next door.

At sunset, there were clouds above us, rain in the east, and clear skies to the west, showing a bright orange sun. We looked to the east, and saw a huge rainbow. It was extremely high—it looked like it ought to be an entire circle, even though I knew it couldn’t be more than a semicircle. That doesn’t come through in the one photo that came out, since it’s a matter of perception: neither of us had ever seen a rainbow centered at the horizon before. It was also faint (I had to increase the contrast on this photo), and 


We stayed at the Rio, which has very nice, huge rooms—even if we didn’t spend much time there. The casino floor is also surprisingly easy to navigate, unlike some of the mazes on the Strip. We’re probably the only people to stay there four nights and not to see the “Show in the Sky” (some vaguely Mardi Gras-ish production they do with floats that run on tracks in the ceiling).
