Slept in a tent?
Yes. Don't like it.

rode a skateboard?
Tried to.

been in a tornado?
Used to go down to the basement and sit under the pool table with my family. Done that many times, but never actually saw one.

played a practical joke?
Yes.

milked a cow?
Dear me, no.

slept in a cave?
Nope. Got lost in one though.

gone target shooting?
Nope.

been in an earthquake?
Felt my actual first one several months ago. It was very brief.

Once in New Zealand, I heard people talking about an earthquake that morning, but I had slept through it.

Similarly, there was one in Chicago (a very rare happening) around '87 or so that my friends felt but I didn't. I was driving at the time.
