Day 1 of the conference I'm attending. I did two presentations today, my busiest, but was able to sneak away late afternoon. Visited the museum on the site of the 1963 assassination of President Kennedy and took this on my way back. Not a lot of advertising in this area, and no way to create an image without time or resources here. I think call letters displayed like this would count as advertising as they don't seem to serve any other function.
