I'm a 50-something frequent visitor to Las Vegas who likes to stay out late, dancing and drinking and partying. The problem is, the trendy clubs are for people half my age and I feel distinctly old and uncomfortable there (I've tried them). Do you have any suggestions for a little more sedate and conducive scene where I can find people closer to my age?

Now that the Canadian dollar is worth more than the U.S. dollar, what sort of exchange rate are the Las Vegas casinos giving for Canadian dollars?

Part one: "Last night's 'CSI' episode (10/4/07) featured an indoor go-cart track. Is this a real place or was it built for the show? I'm sure the next time we head to Vegas my son would love to check it out." Part two: "A recent episode of 'CSI' featured a murder that took place in a restaurant that was completely dark, deliberately, where the wait staff were blind and the darkness was meant to enhance your eating experience by heightening the taste sensations. Does such a restaurant really exist in Las Vegas? It sounds bizarre, but I'm intrigued."

I was recently in Las Vegas and wondered how many bottles of beer the typical casino goes through daily.

My broker just told me that the Nevada teacher's union wants to increase the gambling tax by 3%. He said that if it happens, casino stocks will tumble. How likely is this tax to happen? And if it does, will it have as dramatic an impact on my gambling stocks as my broker says?

We’re coming to Vegas the Wednesday before Thanksgiving and renting a car. Can you tell us what we can expect from the new rental-car center at the airport?

We are traveling to Las Vegas over Thanksgiving with my mother-in-law, who's in her seventies and cannot walk distances. She'd like to see some of the newer casinos and shopping areas, but they're so huge we were wondering if the hotels or casinos have motorized scooters you can use while you visit the properties, or if there's a company where we could rent one for the week? Also, are there any special rooms in Vegas modified for the blind or visually impaired, as her son is blind?

I've heard that the so-called "secret passageway" to the Southwest Airlines gates at McCarran is now closed. Could you please comment on this subject?

I've eaten at the Cafe Bleu restaurant and am wondering if there are any other culinary schools in Vegas that also have a restaurant? I've heard of the Culinary Institue Academy in North Las Vegas. Does it have a restaurant? If so, when is it open and can you tell me anything about the menu they offer?

In the Oct. 7th Q of Day you stated: "It won't be the first enigma hereabouts. Nevada, which has been called 'a vortex of the unexplained,' is home to a number of puzzlements that have occurred over the years." Is there a book or a Web site where I can read about other unexplained occurrences?
