On my first visit to Las Vegas I insisted that we see something other than the neon lights of the strip. So my boyfriend and I drove to Hoover Dam. The drive was beautiful with the view of the mountains and the dry, desert-like horizon. It was May and the heat immediately greeted us as soon as we stepped out of the car. It's certainly worth seeing the dam though as it is quite impressive. As a fun bonus, if you visit Hoover Dam, you can also say that you've been to two places at once. Just stand above the line delineating the state border and snap a photo.
