I am often asked where all these socks came from.  The truth is that I don't know or can't remember. 

There are some wonderful socks stores in the Pittsburgh and Philadelphia airports.  And when you go to a specialty store like one we visited in Northern Wisconsin that had all things moose, you are bound to find some great treasures.  Finally, some of the socks came from tourist stops like Howe Caverns in New York State.  And many were gifts.
