I've been on a couple of road trips around Indonesia, to places where not many white people go. Also I've been on some road trips around Thailand, but they are more used to white people. I went to the casino in Cambodia, just across the border from Thailand. All along the road there are skull and crossbones signs to warn people not to enter the jungle, as it is still full of landmines.
In 2002 I caught the train down to Belgrade with my then girlfriend, I saw one building where you could actually see where a cruise missile had punched a cruise-missile shaped hole through the wall and then exploded further into the building. Some of the locals were really friendly, happy to see foreigners, joking with my girlfriend about her funny accent (her Serbian apparently sounded very funny because she pronounced a lot of words Polish style). Some of the locals were a little hostile. It was interesting.
It's those funny incidental trips to places where hardly anyone speaks English that are the most fun.
