What the hell?
Basically that is how the City of Boston would like their lovely citizens to evacuate. That is if you can spot the little blue signs.
Sure you see them now all over the place because, well, they are posted all over the place, but trust me, you are NOT going to see those suckers in a panic.
And even if you do spot Waldo, it's usually pointing in four directions so good luck to you.
Left, left, left, left.
Right back to where you started.
