and surrounding communities, not to mention Laughlin where it may reach well into the mid teens, Las Vegas proper is expected to hit between 109 and 111 degrees on Saturday, and may very well surpass the record for the day, East Las Vegas will reach slightly higher temperatures than outlying areas. Just remember these temperatures will dehydrate you in short order if you don't hydrate yourself constantly. The human body uses gallons a day in these temperatures. You may carry a water bottle with you into most casinos, I do it all the time, and certainly anywhere on the Strip. There are a lot of places to buy Water but Walgreen's drug store on the Strip and on Fremont Street downtown have always provided bottled water at reasonable prices. You can't have too much of a good thing when it comes to crystal clear water on a scorching hot day. Any AM PM or 7-11 will have water, and all casinos but they charge you more than beer in some cases, and, try try to get drink service at a machine if you're ordering bottled water. Just get some.
