Speaking of doobies: One can imagine the poor luckless gambler, awakening with a hangover and a bad case of post-table stress syndrome, who opens the hotel window curtain and sees this billboard across the street. Medication is just a phone call away.

Gourmet Interlude: Just about every other joint in Vegas “specializes” in prime rib, but for the real deal, you go to Lawry’s. Carnivores looking to celebrate their luck at the casino can expect first-rate service and their cut of choice carved at the table. And the seafood is good. The art deco motif is deluxe, the wine list impressive, and please, “Gentlemen are asked to remove their hats before entering the dining room.”

Few in attendance had ever heard of, let alone seen, a 1903 REX Belt Drive. But Englishman Steve Norton knew what it was, and that he wanted it, and won the bid at $66,000. Not only that, he plans to ride the 2.25-horsepower 344cc Single in this year’s Cannonball Rally. And having served as crew chief for Texans Mike and Buck Carson for two years, Norton is aware of the challenge. “It’s a really solid engine,” he said. “It will take it.” He says the engine will tell him what speed it wants to run. “We’ll find the sweet spot, maybe 25 to 30 mph.” He figures they have two chances. “Either it’ll go or it won’t.” British resolve.
