We love the Tropicana, but nobody seems to know what’s going on there (including the staff our friends have talked to) as to why they're not taking any more reservations after the middle of March or thereabouts. Are they remodeling? Imploding and rebuilding? Sold?

I'm curious as to whether there's been any further information about the recent murder in the Carnaval Tower at Harrah's. National newspaper articles suggested a Las Vegas local shot and killed a Reno resident, who was staying at the hotel. The articles caught my attention, having been a guest at Harrah's a week earlier, albeit in the Mardi Gras Tower, but I haven't seen any further reports.

We were sorry to hear of the Boardwalk closure. What are the plans for the site?

You never did a story about "Sal Sagev" Hotel, which is now the Golden Gate. I would love to know when it was built and when its name was changed.

I heard that the name "Summerlin" was the maiden name of Howard Hughes's grandmother. If so, is the City of Summerlin named after her?

I recently visited The Gamblers Book Club for the first time. It looks like it's been around since forever. How did it get there? Who started it?

There are plenty of lists of popular slot machines (Double Diamond, Blazing 7s, etc.), but I'm just curious about some of the not-so-populars: ones that made it to the casino floor but then were gone like a flash. I know the manufactures do a lot of research, but I'm sure they have had some flops.

Where does neon come from? I know it's a naturally occurring gas, but who figured out that if you get it into a tube and run some electricity through it, it shines in brilliant colors?

Throughout the '70s and early '80s, my parents stayed at Hopp's Motel/Apartments on Paradise. Can you tell me when Hopp's was torn down and what is located on that site now? I believe the owner's name was Warren Hopp.

Who are the Thomas and Mack of the Thomas & Mack Center at the University of Nevada-Las Vegas?
