What does Las Vegas offer besides casinos? Well, since 2001, Pink Jeep Tours has offered off-road tours of the Grand Canyon, Hoover Dam, Death Valley, and other local attractions. They have 10 different tours and are ideal for small groups. They host more than 40,000 guests annually. Besides Vegas, they are also in Sedona, Arizona.
The vehicles are total luxury, including leather seats and DVD players. Tours start at $79. I am so "all over this" the next time that I'm in Vegas.
Have at it!
