Just returned from a successful (won a little and used LVA coupons) trip to Vegas and was driving on Paradise between Flamingo and Tropicana and saw the Thomas and Mack center. Who are (were) Thomas and Mack? Hope I got the two names right.

I know that if a person wins a jackpot of $1,200 or more, he/she would have to claim it on their IRS. My question is: Would a person still have to file a claim with the IRS if that person won several $500 jackpots, totaling more than a couple thousand dollars, either at the same or several casinos in a weekend?

I recently won a $2,400 jackpot at a locals casino in Vegas. Once the slot attendant & staff paid out my money, I really didn't have a clue how much if any to tip her. Should one tip the staff on a jackpot winner? If so, what are the tipping guidelines?

Considering they are in every filling station, 24-hour convenience store, and mom & pop restaurant, as well as casinos ... just how many video poker machines would you estimate were in Las Vegas/Clark County?

Last year I read in a gambling magazine that the Stratosphere is the only casino on the Strip that is in the Las Vegas city limits. I have not been able to find the city-limit boundaries. Can you shed some light on this?

How prevalent are hotel fees and resort amenity fees?

I live in Canada and found a tito cash ticket from my last trip to Las Vegas. The ticket is worn from being in my wallet (unnoticed) and is 11 months old. If I do not get back to Las Vegas, what, if anything can I do? I believe you answered this question awhile back, but I missed reading that answer. Thank you.

My wife is addicted to Diet Coke, to the point where we have to plan our trips around which casinos serve Coke products or someplace close to a "quickie mart" where she can buy Coke products. Why does it appear that Vegas is such a Pepsi-dominated town, and just for fun what volume (compared to a small ocean) of Coke or Pepsi is consumed in Vegas in a year?

Don't any of the pools on the Strip have an indoor pool? I would love to come in the winter, but I want to be able to swim.

Ah, now you've piqued my curiosity. Regarding the old catwalks (QoD 12/21/08), you say, " ... and the risk of surveillance personnel falling over the edge (it did happen, but that’s another story)." So what is the other story?
