The terrain, you could easily trip or twist an ankle.
I did not want any medical problems in a foreign country.
A fewe Colombians came back down the mountain at full spped on the steep slope.
Basically they had to instantly decise to plant the foot and where, because once you start vertically down a steep slope you cannot stop.
Colombians have a strange value on their life, each one could have easily been killed.
Same as driving scooters with 3 or 4 people on it at the same time and no helmet.
