"Stranded"

For a number of weeks, I have seen a skinny guy and this fat lady standing on the island at the intersection of Blue Ridge and I-470. He holds a cardboard sign reading "Stranded: Need Work, Clothes, Food." A few things bug me about this couple. One, they can't be truly stranded on that island because they leave their post and go elsewhere. At times the island is desolate. And they're not truly stranded because you can easily walk away from there and go to a gas station or any number of places. Two, those aren't things I have handy in the car. I suppose I could drive them to a shelter or something, but every time I encounter them it's on the way to work and I'll be late.

Dilemma of the era

Everybody talks about the blogosphere, but nobody says anything about its diameter or circumference. Can the answer ever be found?
