That Invitation for free room, board and entertainment offered by Cal-Neva Lodge at Lake Tahoe to the seven young men who had won $96,000 at Harolds Club was a bit hollow, to our notion. If the seven sue-cessful roulette players had accepted, their identity would be out, and they would be assessedapproximately $12,000 in incometaxes. Since they did not accept, they have a chance to save the 12 grand, and Cal-Neva Lodge gets a free publicity ride at the expense of Harolds Club/
