To thirsty baseball fans at Wrigley Field and the Cell, Adam Carter is the beer guy. But Carter's passion extends way beyond beer and baseball. He is a Fulbright scholar with a Master's degree in international development. But around the ball park he is simply known as beer guy. Adam Carter spends his summers hauling beer cans through the stands at baseball games. It's how he makes his living. But also how he supports his passion: helping others. During baseball's offseason, he travels the remote corners of the world providing food to malnourished kids in Brazil or wheelchairs in Mali. Or mosquito nets in Senegal. He calls what he does micro-philanthropy. Last year he distributed about ten thousand dollars worth of aid in developing countries. But he saw how every dollar was being spent and is convinced he is making a difference one life at a time. Many of his regular customers know about his charity work and contribute generous tips to the cause. Some get a special baseball card that lists some of his accomplishments on the back.
