I have to join those who suggest that a fanny pack is an easy target for thieves to "snip" off. I like to always have something over my shoulder (camera case, men's "purse") that I can also grip with my hand. If you use a fanny pack keep it off the fanny. Get it out there where you can see it and touch it. There is nothing fool proof. They all know who are the tourists are, even without our Hawaiian print shirt and fanny pack. Go in groups and STAY IN THE MIDDLE!
