The Orange River Challenge was the adventure of Brian Gray’s lifetime. The rafting excursion down South Africa’s longest river, in which Gray and his group of 17 encountered 90 kilometers of white water over the course of five days, was something he had never experienced before. In fact, before the 2005 trip Gray never hoped to, because he is a paraplegic. Even more amazing, Gray was not the only unique member of the group; it also contained five visually impaired members and a quadriplegic.
