Car trouble on Mountainside at Mapimi, Durango. It is a long way down if one misses a turn in the road!

We began early Saturday morning & traveled to Mapimi to see the Colonial Spanish era town & the famous Hanging Bridge of Ojuela & the abandoned mine. We began our trip early Saturday morning with Rodolfo & Natalia Duran. The road up to the Ojuela Mine is very narrow & winding & is best driven in autos in good condition which ours was. This is kept up very well but is treacherous & narrow as it replaced a narrow gauge railroad that was in the exact same position going up the mountainsides. At the bottom of the mountain there is a man who uses a radio so that the traffic flow is one way all the time. Once the cars are up at the top of the mountain then the vehicles at the top can leave & make the return trip down the mountainside. We were in good condition heading up the mountain when a small red car with 8 adults packed inside passed us & began to chug up the hillside before us. They were going slow & seemed to indicate there was a problem early on. About half the way up the mountainside the red car started smoking & finally died immediately in front of us. Well, this is a problem on a mountainside! Rodolfo spoke politely to the young woman who was young enough not to worry too much about the delimma her auto placed all the other cars in. After some discussion & walking around the young woman poured more liquid under her smoking hood & began to pull over past our car so she could make the trip without slowing any other vehicles down. She & her compatriots climbed in the car & finally made it up the mountainside apparently unworried about later engine trouble. Hmmm! Certainly not the end to her car trouble I am sure.
