These guys pick a random pay phone (somewhere in the world) and post the phone number. Then they call the number and post their experiences.
http://phoneswarm.com/This week's payphone location: John "Chuck" Erreca Roadside Rest Area (formerly Panoche Roadside Rest Area), 0.7 miles North of Fresno County Line, I-5, California (-120.78334 36.86421). The phone number of the current phone is, as always, displayed via the logo to the left. Here's a short list of all the ways you can work the payphone magic. Don't forget to hit reload in your browser to see the new number if you've been here before.

This is not a great location. It's a goddamned rest area. But I am "okay" with that. I figured it was Phoneswarm material because I walked by and the center phone (of three) started ringing.
"Did you call me?"
"No, actually, this is a payphone. I suspect the party you are trying to reach was calling you awhile ago and has already continued north on I-5. Does this sound like anyone you know?"
"Wuh ... "
Hey, it's something to do this Turkey Day... besides taking a nap.
