INCLINE VILLAGE, Nev. - McAvoy Layne this week filed his 1,000th Pine Nuts column, a weekly Twainesque observation filled with humor, wisdom and opinion.Pine Nuts was first - and always has been - published in the North Lake Tahoe Bonanza, and a former reporter for the Incline Village paper, Guy Clifton, is puoring though the 1,000 columns to compile a book of his favorites.
