We pick up where we left off yesterday, with a foray into the implications, for employees and the workplace, of the legalization in Nevada of medicinal- and, perhaps soon, recreational-marijuana use.

How does medical marijuana affect drug tests for employment and health cards and the like, and what about if recreational marijuana becomes a reality in Nevada, since evidence of usage stays in the bloodstream longer than alcohol?

I have noticed on every major event, the High Roller lights up a different color. How many colors is The Wheel capable of displaying?

Can you update us about the success of Uber as an alternative to taxis from the airport and from hotels on the Strip? Are there any meaningful statistics about ride-share services in Las Vegas or too soon still?

Maybe you can answer a question for all the conspiracy theorists out there. A few years ago, some strange signs started appearing around the city. They look like they are capable of displaying messages in text and people have gone way out in all directions as to what these are going to be used for. Some say highway information; others have said its part of a DHS program called Operation Trailblazer. They are all over the place and none of them are functional (or are they?). Hopefully you can crack this once and for all!

What is/are the name(s) of the mountain range(s) that ring Las Vegas? Is Mount Charleston the highest peak and, if so, what it its official height?

Has ground been broken on the new casino across from the Wynn? If not, any idea when it will occur and when completion is expected?

What are those piles of brightly colored boulders that suddenly appeared by the I-15 outside of Jean?

In the Today's News section, you stated visitor gambling budget was up to $578.54. Is that a day, or visit, and does that constitute a loss or coin-in?

I have another Elvis question. I’m an NV resident. The ONLY thing I like about paying my annual car registration at the local DMV kiosk is when, after I pay, Elvis says "Thank you, thank you very much". The first time I heard it I cracked up, appreciating this rare instance of "the Man," as in the state of Nevada, having a sense of humor. In light of the row going on at the Westgate, I'm curious as to whether the DMV has to pay the Elvis estate for use of his (imitated) voice? And do they have any plans to replace his voice anytime, or switch it out with anybody else (like the Wayner?) Thanks!
