I helped maintain and repair anything and everything that needed maintenance or repair from a kettle to a diesel generator.
No, I got no leave periods – I was there continually for two years, day and night (two of each!). I did not earn a huge sum, but I had two years’ salary waiting in my bank when I returned. I probably earned less in those two years than many people now pay for a decent cabin on a two week cruise of the area. BUT, I experienced it as it really was and would not have missed it for anything (though I would not do it again now!!!). I also visited the Falkland Islands en route in the days before they became famous.
Unfortunately David Attenborough did not visit during my stay. He must have been up the jungle at that time.
