Just came back yesterday from Moab. 103 during the day. If you come bring mucho water, MINIMUM 1.5 gal per person per day, Beer does not Count!, plus some for overheating vehicles. If your cooling system is marginal then dont even consider it to be up to the task. My truck runs 195 always. During the heat of the day it got to 215 twice and I would have to let it cool back off before continuing. I would not plan to bring any small children or we could have big problems on the trails and many of them do not have easy exits (IE hospital access) ((This is a very serious matter they had a biker who was in shape that died in 5 hours out there after getting separated from his group with no water)) so please think your child stratagy . Any wives that can not handle extreme heat would be advised to stay in town or at home. I wheeled from 7:30 P.M. a couple of times to avoid the heat. Shade does not exist in Moab and the red rocks make it even hotter.
