@cwebber The rainforests are, for the most part, not that dangerous. You aren't in the food chain, though that fear was exploited by the prison system on Coiba. If you got sent to that island you'd be put in a different camp depending on which gang you belonged to so people didn't try to escape much first because they were afraid of nature and second because they didn't want to accidentally end up in a rival gang's camp. (they were working on getting rid of the prison camps when I was there)
@wolf480pl @loke @cwebber I was mostly working out of field stations on stuff that didn't require much machete work (at one place I had a military escort who took care of that). Probably the most exhausting from my experience would have been just dealing with the elevation change hiking up out of Cana Field Station, but yeah, it's a harder hike than comparable elevation changes on coffee farms.
