During an enlistment in the US Navy I had the opportunity to visit many exotic (to me) foriegn ports. My goal was to explore authentic local food and culture, but inevitably, the buzz when I got back to the ship was the location of the nearest McDonald's. Some peple just crave consistiency and a "taste of home". Each to their own. If I've spent months to get half way around the planet, I sure as hell want to revel in the experience!
