Walter van Praag, an ambassador for Cystic Fibrosis Australia, born with CF himself, is at it again. This time van Praag, 47, is planning a 5,000 km ride from Vietnam to Singapore to continue raising international awareness for Cystic Fibrosis. The ride is dubbed Viet2Sing and is done under the banner of Coughing4CF, the name Walter uses for his adventures. This is the printed version of the blog kept for the entire adventure (www.coughing4cf.com). Enjoy
