I found a blog post by someone who flew with some of the teams from Johannesburg to Malawi.
The amazing race to Malawi?
The Amazing Race
When I arrived at my terminal to leave Johannesburg, there were approximately 5 guys with massive cameras, and perhaps the same number with large fuzzy mikes. I was curious, but didn't say anything. On the plane, before I switched seats, I was talking to the girls I was sitting next to. They were headed to help their mom with a literacy project, getting oral stories written down in Chichewa. We were saying how curious we were about the cameras, so I asked the guys what the were filming. They said that they were filming "a travel show. It's going to be on tv eventually, but I don't know what channel." That was enough to satisfy my curiosity. But there was a group of teenagers on a mission trip, and somehow they came to the conclusion that it was the amazing race. After I switched seats (there was a lot of seat switching going on), I was sitting next to a girl named Lisa from Holland, and a guy named Andy from Lake Tahoe. We all ended up talking and sharing food from our meals (which were delicious) with each other. It turns out this Andy guy was grouped with the camera people, and as soon as the plane landed, he was off as quickly as possible. My cousin Ryan asked someone later, and it was the amazing race. I wonder what they'll be doing in Malawi...this is my second time bumping into them (first was in Seattle two years ago). Maybe I should start watching that show!
