On the way up mount marcy, in the adirondacks, a forest ranger used to hang out to quiz hikers on the trail on their preps for the trip. Marcy can change from sunny 80's to rainy 40's any month of the year. rangers are friendly folk, but impressive, and the ranger was usually successful in preventing summit attempts by the guys in t-shirts and flip-flops. Maybe the state should sell or rent rucks with the essentials for the trip up, and discount the rescue service charges for purchasers.
