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?

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?

Since Vegas is already perpetually in "Halloween" mode, is there anything special that actually goes on for the holiday there? Or is it just another day in paradise?

Are there any scheduled implosions (of a casino) in the near future? I would love to see one.

I know this question was already answered, but I can not find it in the Archives. How many miles is the Strip from one end to the other?

On our last trip to Las Vegas we saw a "Welcome to Fabulous Las Vegas" sign out along the Boulder Highway. We always knew about the one on Las Vegas Blvd., south of Mandalay Bay but -- are there more of them?

Where can I buy dry ice in Las Vegas? I have burned hundreds if not thousands of cellphone minutes and still ... I live in the Florida Keys and it's available almost everywhere, so I thought with the Vegas heat it would be easy to find out there. But no. Can you help? I'm looking for less than 10 lbs to keep some Key lime pies cold.

I’ve heard that the Las Vegas Strip is a National Scenic Byway. Is this just an official designation, or does it actually mean something?

What is the status of the Hoover Dam bypass bridge? I heard that there were some construction accidents last year and problems with the concrete that might delay the project. Can you give some details?

We know that casino staffers and Las Vegas itself run on tips, which we fully understand and support, when earned. The question is: Are there any guidelines for tipping for various services? We leave $2 each day (in the '80s we would leave $1 per day) for the cleaning lady, but based on your recent information about tipping for valet parking this seems too little. How much does one tip dealers, bellmen/women, cocktail people etc. etc.?
