We took a trip to Las Vegas with a friend to see the Star Trek convention. It was the 45th Anniversary and Leonard Nimoy’s last appearance. We also rented a car and went to the Hoover Dam and took the tour. We also went to an “Ice Bar” called Minus 5. The room was mostly made of ice and kept at -5 degrees C. They gave us coats and gloves when we went in. And the drink glasses were made of ice. The full set of pictures is here.
