My son, Mike, recently had a business trip to Palm Springs, CA. His wife accompanied him as she wanted to hike the desert and expand her photo library. Sounds great, right? Well, when they stepped off the airplane it was 100 degrees in the shade; a dangerous situation. The trails in the Joshua Tree National Park were marked but had major warnings regarding the situation. āDanger, if you attempt this trail, you may die!ā Basically, if youāre not prepared, do not attempt. One park sign insisted that you have liters of water and a full day of food before attempting the trail.
