What, like this moron (left image) that only had a rain jacket and natural buffet given insulation to stay warm, and couldn't light the stove to make coffee for shaking too much???Come prepared for everything.
It's hot right now and it may be shorts weather Thursday through Friday but all of that can change quickly. Be prepared to sleep and be in 40 degree weather and also there could be rain so bring rain gear. Do not make the mistake of just bringing shorts or no rain jacket.
