I love Vegas and the strip. As an east coaster the only thing I notice is my lips will start to chap after 24 hours. Not used to humidity 25% and below. That and the water has a bad taste to it.
We did a 7-11 water run every time we went out in the car. A half-dozen or more liter bottles to bring back to the hotel. It’s really important to get plenty of water in the LV desert climate.
I did some contracting in Iraq, and around this time of year it’s 110+ degrees, and very low humidity like LV. No matter how hydrated you stay, and how much you’re exerting yourself, you don’t sweat. Actually you do. You can feel yourself sweating bullets, but it evaporates from your skin and clothing instantly. You can feel the moisture being sucked right out of your body.
Once I got really dizzy and woozy (air con went out in our office), drank 1.5 liters of bottled water in 10 minutes, and felt great 5 minutes later.
Many (most?) water sources in the west are more alkaline than you’re used to, with high amounts of dissolved solids, especially calcium, magnesium, etc. Fairly typical pH’s are in the 7.5 to 8.5 range. Most water/soil east of the Big Muddy is slightly acidic.
That said, water is where you find it out here. If you’ve never hiked/camped/hunted in the west, and you plan to, you’ll either be packing a lot of water, or you’ll get used to some pretty iffy looking water sources.
I’ve even had to use water from cattle troughs out here. Tastes like crap, but it is still water.
