Thanks @justinparke. It's definitely an adventure. We only did the crossing to go to the supermarket at the shore, because you actually need a 60 Euro visa now to enter French-Guyana, but they tolerate the people of Albina crossing to buy supplies. So if you plan on doing it, don't expect to see the city without a visa.

And I though I was passionate about mushrooms. But that's some determination. Good to hear he made it. If there's anything that soaks up fluid, it's dry mushrooms.
