I am from a small town and have never used valet parking before. I will have a rental car while in Vegas and wanted to know if you can use the valet parking at a hotel on or off the Strip that you do not have a room at. Also, please explain proper etiquette for using the valet service.

This is an off-the-wall question, but do any of the spas in Las Vegas have oxygen bars or, for that matter, are there any oxygen bars on the Strip? A friend and I tried one at the Mall of Americas in Minnesota and loved it. We are coming to Vegas in November so wanted to know if their are any there?

My family and I will be in Las Vegas in late July. Unfortunately, my wife has a problem with heat. What cool things are there to do during the day?

You get a lot of questions concerning tips. I once heard that "TIP" is an acronym for "To insure promptness" and was generally paid in advance of the meal in Europe. Any truth to this?

In Today's News last week, you posted a short item about the Springs Preserve. Can you tell us a little more about it?

The smoking ban controversy: reader feedback.

Not a question, but a comment on QoD 5/31/07. You wrote, "Thousands of people have complained to the Health Department, which not only has no enforcement teeth (its agents are unarmed) ..." What would you have them do, shoot us smokers on sight? Maybe prison would be a good option- - "Whaddaya in for?" "Me? Smoking a cigarette." I always loved Vegas because it was one of the last true refuges for smokers. Guess I'm too un-PC. Maybe, with any luck, all us smokers will die off in a great mass extinction. That would make the rest of you real happy. Let freedom ring.

What's up downtown? My sister, a friend, and I were out late the other night and wanted to grab dinner around 10:30. It seems all the restaurants were closed ... last seating at 9 or 10 even in the casinos. Any suggestions for late-night sit-down grub downtown?

Why are we so hooked on slots?

It might be a little early, but is there any special events happening in Vegas the weekend when it will be 07-07-07 (July 7, 2007)?
