From the files of "you can't make this stuff up," five hikers from Miami got lost while hiking in the Adirondacks and decided to keep each other warm in a strange and interesting way.
"As it grew dark, temperatures dipped into the 40s and rain began falling. The group tried to keep warm by urinating on each other, they told rescuers. The technique is not a standard survival technique and apparently provided limited relief."
