I would love to visit Las Vegas. I haven't been there since I was very young.
It is the 28th most populated city in the US.
Is it pretty expensive to live there?
I am not sure but it is the largest city within the Mojave Desert.
That is interesting. What are some sites that I would want to see there if I visit?
Depends, do you want to gamble, shop, eat, be entertained or experience the nightlife
I am interested in entertainment and night life.
You should go to one of the mega casino-hotels.
What are some of them called?
There are too many to name, but Las Vegas is one of the most visited tourist destinations in the world.
