the Whites will kill you in the middle of summer with the cold. I lived in ME, MA and NH my whole life until this past year. I have seen near freezing temps in the summer in the Whites. Okay, maybe it wasn't but I wouldn't have wanted to be without shelter. 3 years back, end of June, hard rain all day, cold night. Good thing I was tenting at a campground and someone had spare blankets for me because even though I was on a COT, and in my sleeping bag, it was FREEZING! If I had been hiking all day and been wet and sleeping on the ground without spare blankets I would most certainly have suffered hypothermia.
