Have you ever wondered how people cross the street during the Boston Marathon? Well, I can tell you that based on the video you are about to watch- it is very tricky.

Since the BM is a timed race, they cannot just stop runners in their path to let a group of pedestrians cross. So, what they do is divide the road in half. The runners are diverted to one side of the road while the pedestrians come halfway across and then wait inside a painted box, like a gaggle of pigs waiting for the butcher. A gaggle, Matt.. really? After they're all safely contained within, the runners are then diverted back over to the other side of the street and the pedestrians can cross safely to the other side. Check out this time-lapse video of exactly how it's done!
