I just thought this was a good picture of GRC representin' at Boston circa 15K, so I am sharing.
Below is a rough transcription of what was said around the 15k mark.
Reaves: "look up they're going to take our picture"
Murphy: "everyone smile"
Klim: "this will be great, all four of us will be stride for stride in one photo. This is a sure bet for a good blog post"
