(Seattle, WA)  --  The so-called "Man in Tree" is now back down to earth.  After more than 24 hours atop an 80-foot Sequoia next to the 4th Avenue Macy's in downtown Seattle, the man finally climbed down yesterday.  After he went up the tree Wednesday morning, police and firefighters tried unsuccessfully to talk him down, and he responded by tossing tree branches in their direction.  Traffic was blocked off Wednesday in the area of the Macy's as negotiations dragged on.  The man was taken yesterday to a hospital for a medical and mental evaluation.
