Box.

Living in the concrete jungles of Chicago for the majority, one could only imagine the truest importance of that little red handle.... 

You know, that thing that lays somewhere on the right side of the mailbox. Lol.

Yeah, the vintage type.

Never really knew the actual purpose.....ok, ok...Pull the red handle and boom the box opens. 

Not!

Now I know...

No need for the blue public mailbox 2 drop off when you have your very own trusty red flag. (funny.)

Guess "Chicago" can actually learn something new from time 2 time.

No matter how simple.

Yep!

Peace!....with 2 fingers;)
