The journey from Panama to Colombia is notoriously dangerous by land, through the Darien gap. So, being a safety-first kind of girl, i´m gonna avoid the guerillas and go by sea instead :)
The Captains that sail the boats from Panama to Colombia, however, are generally a bit dodgy. This guy has been recommended by a few people and has connections with the hostel where i´m staying in Panama City.....but just in case i get tipped overboard halfway down, i thought i´d make the investigation a little bit easier ;)
