I really like the Springs Preserve.  This review would have been 5 stars if the Preserve still had the \"Untold Stories\" series on the first Thursday of the month.  These programs about the history of Las Vegas were wonderful, but the Preserve decided to re-evaluate their educational offerings.\n\nI love the Origen Building with its movie \"Miracle in the Mojave\" about water and the lack thereof in the Las Vegas Valley.  It's a brief film, narrated by Martin Sheen, and it quite nicely relates how the area came to be what it is geologically.\n\nThe flash flood in the Origen is also fun to see.  When it's not too hot, I like to go in the back and see the animals in the fenced area or in the display domes.\n\nI need to go back and hike the trails again to see what has changed from when they opened.
