In the April LVA, you refer to an "insta-comp" at Rampart. Earn 1,000 same-day points ($2,000 coin-in) and get a comp for a choice of four different meals. You say the expected loss is less than $10. Can you explain how that is calculated?

How come I haven’t seen any solar panels on homes in Las Vegas area?

Las Vegas resort-casino opening attractions and their fate: Part II

I was just in Vegas, walking through the front entrance to Excalibur, and had a vague memory of a show in the moat out there. It seems like most modern hotel/casinos opened with some sort of a free show or attraction. The pirate show at TI, Bellagio Fountains, Mirage Volcano, Lions at MGM, etc. I was wondering if you could put together a rundown of all the current properties, what attraction (if any) they opened with, and how many of those attractions still operate.

Since the big fanfare when it opened, I have not heard anything about the Elvis Exhibit at the Westgate. How is it doing?

Just returned from Vegas (4/29), and wondering if anyone is monitoring the costumes/outfits of Fremont Street participants? While most are entertaining, some seem uncomfortably bizarre ... especially with young families enjoying the activities.

A few years ago I enjoyed going to Mandalay Bay to see the Komodo Dragon at the Shark Reef. On a recent trip to Las Vegas I noticed that the Komodo Dragon billboard and all of its advertising seem to be gone. Is the dragon still there, on display?

About two years ago, there was a rumor that The Amazing Jonathan had been contracted to revamp the Las Vegas Club. Any idea what ever happened with that?

Can you find out what happened to Trent Carlini at the Westgate? He is by far the best Elvis impersonator around and I can't believe that he isn't going to portray Elvis in the new show at Westgate. Thanks.

Speaking of Walks of Fame (QoD 4/21/15) there was a jazz walk on Tropicana, across from the Bally's parking lot. What was that all about?
