My sister Monique reminded me of the best picture from 2008, which is worth a post.
This is from the finish area of 2008 Chicago Marathon. While 08 was not as hot as 07, it did reach the low 80's and people were suffering at the end. Shannon got a shot of this guy cooling off on a stack of beer, with an ice bag on his head. While it looks like an ad for "312" beer, it is still captures the post-marathon pain and bliss.
