These mysterious boxes, powered by car batteries, are popping up all over New York City. There's no cause for alarm, of course, but something's definitely afoot.


That something being the New York Marathon, which was run this morning in the chilly November fall air:

The boxes are tracking equipment, and this particular one was located at mile marker 6. Nothing too crazy, but it's timely, and there was even a brave Chilean running this year! [Thanks, Alexander]
