I like gambling at the Fremont Hotel in downtown Las Vegas, but the last several times that I have been there, I have noticed a strong vibration in the women's restroom near the buffet. The vibration is so bad that the stalls are shaking and rattling. It has been like this since at least June of this year, when I first noticed it. It could be longer, though. I am just wondering if an old building like this can handle a strong vibration for this many months without damage being done to the structure of the whole building. It feels like a constant earthquake that never stops. Can you check this out and tell me if this is something to worry about? I feel like it could collapse at any moment.

Is it me or has the M tightened up its slots and video poker machines? The last half- dozen times I have played there (over 6-8 months), my money has evaporated a lot faster than in the past. Is there any way that the state of Nevada can check on the validity of casinos claim on payouts?

Some photos of Fremont Street from the 1960s show the signage at the Las Vegas Club as, "Biff's Famous Las Vegas Club." Who the hell was Biff?
