Last week I posted advice about rain gear. I meant anything from a cheap poncho to full on rain gear. If you don't have a good jacket, a poncho will do. I see a lot of day hikers making it to the top and they are completely drenched with no dry clothes to put on. The temperatures on the mountain are much cooler, especially when you are soaking wet. Ponchos do not weigh much. Most of the time they can fit in your pocket. It is always good to be prepared when out in these mountains. You never know what kind of weather you are going to experience.
