Be careful when you return from Mazatlan next time. We hit this pothole that was cleverly disguised as an oil slick and that is shaped like a medial section of a car tire…. and deep! Luckily, we were in the truck and its extra wide tread did not fall into the cavern that exists below this oily facade. But a regular tire might be another story, so watch out. It is located just before the entrance to the Mazatlan Industrial Park, southbound I-15. If you stay in the left lane, you’ll miss it, but you might also miss the turn! Right laners are in danger. This thing will rip your tire to pieces!
