I don't know who Richard L. Hall is but this does come from a 1988 Gun Dog magazine so may be the same Richard L. Hall.Who is this "Richard L." Hall? Last time I saw his byline was in an early 90s issue of Gundog Magazine that featured an advert for (yeah) "Pointing Boykins."*
* "Richard L.'s" editorial content had nothing to do with this ad, though I seem to recall he was writing about a "spotted Lab" (a/k/a his Brittany, Kai, as a topnotch retriever for Rick's waterfowl guiding on the Bayou, but I may be mistaken)
J, he's rtf's own just plain Rick Hall, a working Chessie fancier and a longstanding contributor of good and occasionally thought-provoking training and fowling info--I don't know who Richard L. Hall is but this does come from a 1988 Gun Dog magazine so may be the same Richard L. Hall.
