I'm sorry I haven't posted this yet, but it's worthy of a mention.
When Connecticut Joyce and I were driving to New London for the 3rd Senate debate, we stopped at a highway rest area for a break. CT Joyce went to the Ladies', and was in there for quite a while.
When she came out, she was laughing. I asked what was going on, and she said that in each of the stalls, someone had written graffiti that said, "A Vote For Joe Is A Vote For Bush".
She wanted to check to see it was on all five stalls (it was); I guess she would have come out for a Sharpie if the message didn't appear in all of them.
So, we have "Freeway Blogging", and now we have "Bathroom Blogging". Funny how things eventually come full circle.
And I don't have a photo of the one CT Joyce saw, but the picture below is one of my favorite examples of "bathroom blogging" (people used to call it "graffiti").
