Hey guys,
Just passed through Central America, currently in Ecuador on the way down to Ushuaia. As far as Central America, I just thought I'd mention two things:
1. Get more than one International Driving Permit. If you get stopped and hassled by the police anywhere in Central America, they will almost always ask to see your Driver's License first. Then, they may tell you to go to the town, pay a "fine" if they claim you broke a traffic regulation, and return to retrieve your Driver's License. In a pinch, if you have a couple International Driving Permits, you can always drive away, and just leave the Permit with them. I only brought one, and I wish I had brought more. Just an idea.......
2. As far as security, besides taking a little extra care in El Salvador, the only place to really keep an eye on is Honduras, as they have been having some changes in government lately. It's not dangerous, but they did close the border a few times with the elections, so make sure you check that it's not closed when you are planning on crossing.
Other than that, just keep your wits about you, don't drive at night, don't get stressed out when you get stuck behind a slow, exhaust belching bus on a curvy mountain road, and you'll be fine!
Ride safe, feel free to shoot me any questions you might have, and you can check out the ol' blog at Pura Vida 2009-10 » New York to Argentina by motorcycle…… if you want some commentary.....
