It's fun to randomly come across an update on a story featured on KarmaTube. Two years ago, we featured this story on 10-yr-old Zach Bonner: http://bit.ly/aOdKwQ At age 6 he founded a charity...and now at age 12 he is walking almost 2,500 miles across the U.S. in support of it: http://nyti.ms/9Jv7Iv This kid is serious business -- he wakes up at 3:30am everyday and starts walking at 5am.
