I know that in Nevada and presume that in other states, slot machines are regulated to minimum payouts over time. Are casinos on cruise lines under any regulation? And what about those that are associated with Nevada gaming conglomerates? I believe that Caesars Entertainment is associated with a cruise line. Do they "self-impose" betters odds for casino players on those cruise lines that have a land-based connection?

Happy Easter.

About when did the first resort fees arrive in Las Vegas and about how much do they add to the total income per day, week or month now? Are there any records to show year-by-year progression?

Re the recent Baker, CA QoD answer, my daughter-in-law was raised in Victorville and said there used to be a prison in Baker. True or not?

Any update on the possible strike at the downtown casinos?

I seem to remember seeing documentaries of the building of the Venetian hotel and also one on the behind-the-scenes operations of the Rio. I have tried to find them but have had no luck. They could have been produced by the Discovery or Travel Channel. Can you help? Thanks.

If they can put a man on the moon, why can't they make replacement parts for the Sigma Derby horse-racing machine?

In celebration of April Fool's Day, we are finally delivering on a long-overdue promise to publish some of the silly or nonsensical queries that grace the QoD "in" box from time to time, together with our hypothetical answers. It's all just in the spirit of some harmless fun, so please don't anyone take offense, should you find a question of yours below that was submitted in all seriousness; instead, take gratification that you know your goof is giving others a healthy giggle.

In "Today’s News" (March 27), you said Harrah’s Tunica was closing because "the casino is losing money." In the same sentence, you stated that it brought in $723 million last year. How do you figure $2 million/day revenue is a losing proposition?

I just took the tour of the Neon Museum Boneyard (a wonderful experience). It got me thinking about other Vegas signs and symbols, and I was wondering if anyone knows what became of the camels that used to be outside the Sahara? An article written during the hotel-liquidation sale mentions a listed price of $12,000 each. Do you know what became of them?
