I agree that the best way to insure the preservation of Mike's knowledge is for him to publish everything that he has in a book or books. I'll take 2 of each that he publishes,maybe more. I have the habit of buying multiple copies of books that I find well researched in subjects that interest me.Most of the time they are not best sellers but time has proven that they become sought after in time.Witness the price of John Bivins book on North Carolina furniture and the original Colt and Winchester engraving books.
