A couple of weeks ago I took Hwy 15 up to Nogales from Chapala. Roads were excellent and should be considering the amount of tolls one pays during such a trip. Seemed like there was a toll station every 15 minutes. Well, a lot anyway.
Although I have driven this route alone many times I chose to use a driver this time as back problems have me pretty much incapacitated. We planned a two day trip, one day to Los Mochis and then one more day up to Nogales. All went smoothly until, between Guaymas and Hermosillo, in the middle of the desert, my car started overheating and we could not continue. A hose had come loose and all my coolant had escaped.
I had no auto tools with me and only a liter of drinking water. We were stuck for about three hours and no passing cars would stop to help. With good reason as most Mexican travelers are afraid of each other and stopping to help a stranded motorist is not part of the current culture. Apparently two big guys standing in the road waving empty water bottles did not inspire confidence. Calls to the 074 emergency number got only vague promises that perhaps, in five or six hours, a tow truck could be sent out from Guaymas. Not very helpful and the famous Green Angels who used to patrol the roads are nowhere to be seen these days. Incidentally if you don't speak and understand Spanish you will have a very, very hard time calling for the help that's maybe never going to come anyway.
Finally I remembered that there was a Leatherman tool somewhere in my luggage and with it we were able to re-attach the loose hose. But we still had no water. After close to three hours a pickup stopped across the hwy in the southbound lane and Felipe my driver ran over and caught him before he could take off. Fortunately he had a two gallon jug of drinking water that we were able to buy from him and that allowed us to limp into Hermosillo and refill with coolant. Note...this guy didn't stop to help us, he was reading a map when Felipe started knocking on his window.
The moral of this story is that if you are going to drive across that desert you should be prepared to handle any type of minor breakdown yourself because it's very probable that no one is going to stop to help you. At least that was my very recent experience. Take tools, several gallons of water and spares of any parts that are likely to fail on the trip
I had never had any type of problem before on any of the many trips I've made through Mexico over the years and had become complacent. I will be much better prepared should I ever make this trip again.
