France. I was in the military and driving my truck near Kaiserslautern, Germany and missed a turnoff. After a bit I notices that the cars had amber headlights. I'd accidentally driven into France. Surprise!
15 days visiting Costa Rica in the early 2000's. They were just becoming big in the tourism world. Tons of fun.
Turks and Caicos as a close 2nd. (Before they were hit by that big hurricane.)
China '07.
Went to sing Karaoke, we ended up in a brothel, with some dude dressed like sgt pepper trying to get us to pay for his " wonderful girls". Avoid KTV places.
There was also a urinal at a rest stop that was an active fish tank.
I'm boring and have never left my home country. I'd be up for traveling one day if I found a partner who liked traveling, but it's not something I'd ever do on my own, and I don't know anyone who wants to travel.
