Las Vegas is not the best place to take photos of natural beauty. However, you cannot find a better place to do so driving a short distance from the city.
I would think there would be very dramatic landscapes near Las Vegas. Is that true?
Yes. Even "the most beautiful scar on earth," the Grand Canyon is not far from the city.
About how far from Las Vegas is the Grand Canyon?
The Grand Canyon is about 130 miles away from Las Vegas. 
Is there any cool places to stop between Las Vegas and the Grand Canyon? Maybe places to take nature photos?
Once you drive out of the city, it seems everywhere between is a great place to take pictures. The rock color and formations are different at every direction you look.
Do you ever hike around the Grand Canyon to take photos? I bet it's a challenging workout.
I did many times. Indeed, that is one of my favorite activities. There are so many trails at Grand Canyon. Hiking down the Canyon and seeing the changing scenes are amazing. But you are right, it's not easy for everyone, especially you have to hiking up back. 
Living in Las Vegas must be fun. All those casinos! Do you gamble?
I don't like gambling. In fact, I have never play a casino, though stayed in some casino resorts. Do you like to gamble?
We have a small casino here. I go when my mom visits. About once a year. Well I need to go now. It was nice talking to you.
Nice to talk to you too. I hope you can come to visit Las Vegas. Have a great day.
