A black bear has been showing up in a neighborhood outside L.A. for a month, and yesterday morning authorities finally caught it.  But not before it gave one resident the scare of his LIFE.  (--It happened in La Crescenta, about 10 miles north of L.A.)  The guy heard helicopters, went outside to see what was going on, and came face-to-face with the bear.  But he didn't see it until it was about ten feet in front of him . . . because he was walking and texting. A local news station got it all on video, and the anchors immediately started laughing.
