2. Slept under the stars
That was the second item on the list, the first being whether one has started a blog. Well duh, wouldn't everyone who were to pick up such a meme be a blogger by default?
Regardless, I've never done it: never slept under the stars. But I have certainly slept in a tent, and I think that's pretty close.

While I'm almost certain that I have posted about the trip previously, I can't find it for linking purposes. Nevertheless, I'll cut the account a bit short and refer only on our very silly sleeping arrangement.
You see, this is bear country, and bears do like to scrounge about in campers' food supplies if they can possibly arrange it. My friend decided that, in order to protect our provisions, we should sleep with the food in the tent. While I thought it odd, he was the experienced camper, so I didn't question him. How would I know that you're supposed to hang your food pack out of reach in a tree? Otherwise a bear could possibly crash into the tent and maul those who stood (er slept) between him and a midnight snack. It was a very bad decision that could have led to disaster, but no bears sniffed around, and both we and our food remained safe.
This was to be my only experience of wilderness camping but not my only tenting experience, but I think that's enough for one post.
