If you are looking for something different to do in Vegas, try the guided Mountain bike rides by McGhie's. A great way to learn the Red Rocks mtn bike trail system. Had Matthew as my guide, what a great deal, picked me up at my hotel on the strip at 8:30, we were riding buffed singletrack by 9:15. Great variety of trails and not a lot of climbing to get some really long downhills. The trail system is so varied, can easily find something for everyone from beginners to experts. A great way to detoxify the body after a couple of days on the strip. Beautiful scenery, great guide, great bikes, awesome trails, you can't go wrong with McGhie's!
