This is not RV related but falls in line with the thread topic.
A few years ago, a few friends and I planned a surf trip down to Panama (not Florida, actually Panama). The trip consisted of flying into Panama City, then taking a chartered bus ride 6 hours north and west to a very remote area on the north coast of Panama. From there, we got on a boat and it was about an hour boat ride to an island where the surf camp is. Spent 1 1/2 weeks there, leaving the camp and took the hour ride back to the port. While back at the port, my friend heard a guy talking, who was not with our party, and said he thought he recognized the voice. Turns out this guy used to be my friends immediate next door neighbor from 3 years ago.
It was very odd but a situation/story I will never forget.
