Let me help you with the flat tire
(that I just made go flat)
Easter Week 2010 in Chapala, a tire was punctured on a car, and when the vehicle occupant pulled into a car wash with the flat tire, her purse was stolen. And about 10 days later, a Lakeside couple had their tires punctured while visiting Guad - and the end result was that they, too, had personal possessions stolen. Plus we have heard more stories.
So be aware - if you experience a flat tire, probably best to NOT accept the help of strangers. The flat may have been deliberately created to set you up for theft of your personal possessions in the vehicle. When you experience a flat tire, it is only natural to be distracted by the problem. That is what they are counting on.
