My spouse and I both retired from teaching last year, and for religious and other reasons have never gambled in a casino. We’re invited to speak at a convention at Caesars Palace next month. We’re tempted, but…. What do you suggest? TRMcD, Ogden UT

A: Unless your religion expressly forbids it, go to the convention. Of course, its called Sin City, but there are countless other things to do in Las Vegas besides gambling, and many are free. For example, check out Fountain Shops and art displays at Caesars, as well as downtown Fremont Street where there are nightly sky-filled lights, music and huge projected images.

There’s the Conservatory at the Bellagio Resort, with beautiful blooming trees and flowers, huge aquarium at the Silverton Resort and interactive art museums at the Cosmopolitan and City Center. And don’t miss the Statue of Liberty at New York New York and Grand Canal at the Venetian. And, if you have the time and interest, there’s much more to enjoy.

When you pick up the phone, there’s a friendly voice, and it frequently begins with: How are you today? For your travel4seniors.com editor, the immediate reply is a loud curse and quick slam of the phone. That’s the safest way to protect yourself from being robbed.

However, if you cluelessly decide to listen, as millions of senior suckers do, the voice offers all kinds of goodies, often including that you’ve just won a free cruise. Of course, you should then realize the wise old saying: there’s no such thing as a free ocean ride.

The next step in the scam is requiring you to send in your credit card and other personal info. That’s when you’ve foolishly set yourself up for online robbery. Whenever you plan a voyage, always deal directly with the cruise line or a trusted travel agency.

It had to happen sooner or later! With all the hoopla about automatic cars on the roads, soon you’ll be able to hail, hop on and hop off a driverless taxi. It could happen in a city wherever your future travel schedule takes you. As with Uber and Lyft, you’ll call with your smartphone app and go for a ride.

And just maybe, the inventors of the new taxis will add familiar features from traditional taxis to ease your ride. Such as: When you tell the automatic driver your destination, you must speak in a foreign language of taxi driver’s origin, such as Brazilian, Swahili or Mogadishu. Also, from the back seat, you’ll smell the automatic driver’s unwashed odor of sweat, flatulence, garlic, wine, chili or week-old fishcakes.

When you enter the Waymo cab, it will automatically take you on the longest and most expensive round-about route. And if you ride on a busy traffic evening to a downtown restaurant or theater, the pumped-up tab will be double the daytime rate. Finally a question: How much do you tip a non-human driver?

This unposed photo by your travel4seniors.com editor illustrates how the no scooters on sidewalk sign is ignored by thoughtless riders of the grown-up kiddie toys. While adult and child walkers are trying to avoid racing scooters, they may stumble over a stack of abandoned ones spread across the sidewalk waiting for new reckless riders.

City scooters are supposed to be limited to 15 mph on the street, but single racers and mindless groups of them go much faster illegally on sidewalks. So, in your city travels, if you’re an elderly and physically challenged hiker, be alert for speeding scooters racing illegally on sidewalks and busy street intersections.
