You might have heard something about this, it was on the news when he started about two weeks ago. My friend Stephan Wanger is, for charity and other reasons known only to himself, biking to South America, actually biking 25,000 miles total which means a circuitous route that currently has him in New York. Since he's now been gone for two weeks, there's enough news to make his site (maintained by another friend) interesting to visit. So, check it out:

Click on the weblog link to read his reports from the road, they're pretty interesting.
