During our 4-day Las Vegas trip at the end of June, my husband and I took the easy drive from the Strip to visit this place and were delighted with everything but the heat outside (duh!). One brilliant touch: The parking lot is completely covered with solar panels so 1) your car doesn't get hot and 2) power is generated for all the interactive exhibits in the museum (which means they "walk their talk") and then some. I was most interested to see the xeriscape demonstration gardens--gorgeous and blooming--and ran into an excellent docent named Pete, who gave us a complete tour. Lunch at the Wolfgang Puck cafe was quite good. We didn't get to see everything, but still learned a lot about the geology, history and settlement of Las Vegas. We recommend this highly!
