From Red Rock Canyon National Conservation Area about 15 miles west of Las Vegas, Dr. Mitzi shares how light and dark are a part of us all.  If you are in Las Vegas and have some extra time and want to do something other than the glitz of the casinos check out this area and also nearby Spring Mountain Ranch, both located close to Summerlin. As an added bonus in the hot months it’s usually 10-15 degrees cooler out here because of the higher elevation.  Be sure, however to pack plenty of water and wear appropriate sun protective gear when it’s hot.
