Hey Todd, good Job,It sounds like locking gas caps are a requirement in these parts to start with. The approach you employed is excellent. Cell phones are great tools. In situations like that all they need is the impression you have coverage and you are calling the cops and they will split. My cell has a camera on it, wouldent it be nice to click some photos or the individuals and the cars.It would be kinda cool to do our own little Washington most wanted.
