Last year, I attended an auction in the panhandle of Oklahoma. With only ten dollars cash shoved in my pocket, I bought a box of old magazines and books. Folded in the pages of an old medical textbook, were a series of letters never sent. Written by a man who lived during the depression, the letters are his account of a dust storm in the spring of 1933. Not only do the letters reveal sporadically the lives of those that survived these harsh years. But also offer hints that the man who wrote them had a condition known as synesthesia.
