My friend Glenn spreads the gtospel of roadchalking with this catchy title:

I had a friend in high school who's grandfather was the King of the Hoboes. No, really. He made us a kind of soup once, out of flower stems and water from a garden hose.
(Hmmm. Hobos? Hoboes? Spellcheck doesn't know...wife is asleep...online dictionary isn't saying...grrrrr.)
And in a related story, one of my favorite parks has WiFi now, because this city is so damn cool. They have great movies at Bryant Park all summer long, and now I have an excuse to get work done while I am waiting for the film to start, holding a spot on the lawn. Multitasking!
