If you haven't been checking out Dev's adventures in South America, you should be. He's there for a language immersion program and training his butt off. And bringing home bling, too.
Then there's Christian Graugart. He's a Danish brown belt who writes a great blog and is now leaving on the kind of trip I dream of-- backpacking around the world and grappling everywhere.
Check out Christian's blog for the trip, BJJ Globetrotter, and let him know if you can help-- where should he train? competition coming up? got a couch he could crash on?
