When I was a kid my two favorite books were:

Sinbad and Me by Kin Platt
and
Two Against the North by Farley Mowat

when I was my son's age (13) my dream was to go off into the canadian wilderness and live my life in the wild.

Last year, my wife found the books and gave them to me for my birthday.

Sinbad and Me was especially hard to find and ended up costing her $95. Those two books are probably the two best presents I have ever received.
