I was just surprised that when I typed in Moby D-i-c-k, it came out Moby ****. Is this some kind of electronic censorship program which has decided that D-i-c-k is a dirty word? If my name was Richard, I think I'd be insulted. Sparse Grey Hackle was the nom-de-plume of Alfred W. Miller. I know I've got some biographical info around here someplace but I can't find it just now. He was editor of The Angler's Club Bulletin (New York) for nearly fifty years and campaigned against pollution and degradation of rivers and streams in the Catskills. He's probably best remembered for his collection of stories, Fishless Days, Angling Nights. That's about all I can find offhand. The only book I've read lately that I'd recommend highly would have to be Tom McGuane's The Longest Silence.
Tight lines and good reading.
