The city is often pretty dead on the 4th of July (the east side was anyway).  I went to several Starbucks establishments throughout the day to either cool off or just hydrate, if not momentarily, but they were all pretty empty.  Again, the city as a whole was pretty empty but I figured Starbucks would be packed with people trying to escape the heat but it was just the opposite.  The few people I saw in the various (otherwise) "hot" spots were pretty listless (likely from the heat) and nobody seemed very interested in much of anything - not each other; not even themselves.  They were just sort of lingering in the misery of this ongoing heatwave that I think we're all just getting a little tired of.  Can you blame us?
