The Highest Challenge Project is an ongoing expedition to climb the highest mountain in as many of the 193 countries of the world as possible. Already holding the world record for being the first person to climb the highest mountain in every country in Europe (47 countries) and 51 out of the 53 countries in Africa, Ginge Fullen also holds the record for scaling the highest mountain in more countries than anyone else to date, presently 118 countries. The following article from Fullen describes his difficulties in scaling Serra Moco, the highest mountain in Angola, because of landmines.
