In Yangshuo, China (google it: the most beautiful place on the planet), I got into a rickedy old Jeep with the owner of my hostel, a guy from Dallas, my boyfriend, and 2 friends. We drove through a bamboo forest in the boonies, out past some villages, and found "the secret spot" of the Li River. We went tubing all the way into the downtown area of Yangshuo (we washed up at a somewhat posh restaurant, haha), going through rapids, stopping to jump off cliffs, etc. It was the most spontaneous, potentially deadly thing I ever did, because we barely spoke Chinese, they barely spoke English, and we agreed to get into a car with them and go tubing lol. They could have kidnapped me or murdered me and no one would know .. But instead I had the best experience in my whole time in China.
Shortly after that, we rented motorcycles in a back alley, with ZERO EXPERIENCE, and rode all over the countryside, through villages and mountains, going to hot spots like Moon Cove (again, Google it .. crazy beauty), etc. It was exhilarating.
Sorry for the novel!
You have the house/apartment to yourself, no kids, no spouse, no family, no nothing, nothing that needs to be done .. What do you do?
