Why does George tell Leanie to remeber the spot where they are camping?no

If I recall correctly, George tells Lennie to remember the spot so that he will know where to meet should he get into any trouble.  George wants Lennie to have a safe place to hide until he can help him.

Ironically, it is in this safe place that Lennie meets his end, and George is the one who takes Lennie's life.  He does this to help protect his friend from an even worse fate--being caught by Curley and the lynch mob.
