It's a little known fact that hikers and picnickers, not paddlers, are the most likely accident victims at riverside parks. The National Park Service Morning Report for August 4th stated that Babu Gurusbrami, 27, lost his footing and was swept away while wading in the Class I-II Chattahoochee River near Atlanta, Georgia. Search teams found his body several days later.
