I Love Riddles

Here it goes:
20 prisoners are made to stand in a line, all facing forward and none allowed to look behind himself. The evil warden places a hat on each prisoner and all the hats are either red or black. Beginning with the last person in line (who can see the 19 people ahead of him) and moving person by person to the front, the warden will ask each what color hat he has on his own head. Those who are wrong will be executed.
Devise a strategy for the prisoners which will guarantee the safety of as many as possible.

No coded signals are allowed, no coughs, sneezes etc. All of them would be executed if anyone tries anything fishy. They can only utter the color black or white whatever they think is on their head.

@ArtistRajaBhaiya Yup! You've got the name right and are on the right track when it comes to the town; it's Andover, Massachusetts.

Allegedly (I doubt it's true) an envelope came into a United States Post Office addressed in an unconventional manner. It read as follows:

Wood
John
Mass

The envelope was delivered to the correct address and person. To whom was the envelope addressed and where was its destination?

I have a brilliant one. But it is a pretty long narrative! And if you are seriously into puzzles it might be an old one for you. But if you ate interested, I can find it online and paste it here!

In and out like the tides I go, past the jaws I move to and fro. If you lose me, find me fast, or else my loss will be your last! What am I?

I would love to read it, thank you.

(and if I have seen it before I promise not to spoil it for anyone) :D

MrTimothy is it something like John Underwood??? I can't complete the address though! Over Mass???

Where do all the odd socks go??
(NB I have no idea either)
