I met up with Zimbabwe Smurf AKA Dave Sherman in Denver a few years ago, just a few months before he was to move to New Zealand and in his words:
arrive at the almost-empty airport at 7:00 in the morning, sitting in the lobby, hungry, cold, tired, with our backpacks and nothing else. We had nowhere to live, nothing to do, no one we knew, no car, no warm clothing. Remember this feeling. It is the meter-stick by which to measure our progress.
I follow Zim on his occasional blog. You can too.
