Yes, I went to the Carson Valley Inn show too. Forgot about that one.

The Harvey's Lake Tahoe show was in June 1991.
The way I remember is because Deadwood casinos had recently opened and I picked up a number of Deadwood chips at that show.

The show was in a 2nd floor meeting room, as I recall. Not as big as the Bellflower shows of that time. About the same size (in square footage) as the current SuperBowl shows. Bruce Landau offered some soft prices on Nevada and NJ chips. What a guy, a real "mensch"! I miss him.
