I think that would be a great day to hike Whitney, I bought this book and it said some very stupid things about expect to come down in a snow storm and in the dark . How could that be? It talked about a temperature drop of 43 degrees in one hour ,bears and all sorts of nonsense stuff that you don't find in the park, and then it went on and on about rescues and how it all takes a long time and you know stuff like that was just filler, the book has good pictures but I think they are fake just to scare people into leaving extra food at home or is a joke on the people that try to fit a pickup load into the bear box, did I mention the rescue thing? Oh the book said sometimes people die on the mountain , must be drive by shooting or something again how could that be? Maybe I will write a book someday ( after I figure it all out and get some good pictures) maybe call the book the real mountain lore from the cooks world. Thanks Doug
