Now that I’ve got a scanner. Here is an old photo from the helicopter (not taken by me though). It is from around 1994 when I was living in Colombia and flying around to the sites in helicopters. The pump station is, if I recall, Ecopetrol El Porvenir. The station is on the top of the mountain and we stayed in a camp at the base. The drive was quite steep. I remember one time I was sitting in the back of the minibus full of people going up the hill and the engine made a strange noise so the driver stopped and got out. Well, it was steep and the van started rolling backwards!!! down the hill which could have been deadly. And I was in the very back, no way to get out fast. But, the alert person in the passenger front seat jumped over and put on the brakes.
