Here is a picture of my old off-roading beast!
I took that thing down many roads that it was not designed for.
On one such occasion, we were on a surf trip down the Baja Peninsula, when the ocean went fully flat. Since surfing was out of the question, we decided to drive across the peninsula so that we could swim in the Sea of Cortez (which none of us had done). Rather than drive all the way back up to Ensenada (3 hours north) to catch the paved highway, we took a "shortcut" that the AAA map described as a "graded dirt road". The road was 40 miles long and met up with the paved highway in [I think the town was called Valle de Trinidad]. Anyway, it cut over some desert mountains where there was nothing other than a few burnt up old cars that had rolled down the steep slope adjacent to the road. This road was so rough that there were many points where the only way to avoid high-centering my low vehicle was to drive with enough speed so that you would slide all the way across the rock or obstacle. To complicate matters, I had put off getting new tires for my car to the point where one of the tires was so bald that the cables were showing. I was fully prepared to abandon my vehicle and escape in my friend's Subaru if necessary.
We were about halfway through the road when a farmer in a truck came driving the opposite direction from us. We found a wide enough spot to pull over and let him by, but he got out and began to talk to us. One of my friends had studied abroad in Puerto Rico and spoke excellent Spanish. They were talking and the farmer looked worried. He said "Ese camino es muy peligroso, y su coche is muy bajo!" [this road is very dangerous, and your car is very low], to which my friend immediately replied "No no, Ese [pointing to my car] es el Baja Especial!" The farmer's son, who was in the back of the truck and until that moment was rolling his eyes and looking bored, doubled over laughing. The farmer simply smiled, shrugged his shoulders, and wished us luck.
What I learned on that trip is that your car can do a lot more than you think. Unfortunately the "Baja Especial" eventually died of a broken frame, I wonder how that ever happened . . .
