Any downsides?
Sometimes – usually when I’m putting all my stuff into storage again. I can’t believe I’ve accumulated so much crap. There are moments on the road when I get a little tired and emotional too. The 60-hour train trip from Khartoum to Wadi Halfa in Sudan on my last trip to Africa, for example, had me wondering what the hell I am doing. But then I get home, see something on the Discovery Channel and I’m all enthused again.
