Ultimate shoulder rides

I had a great experience last night. My sister in law and I were partying last night and we were walking. I joked with her about carrying me. She stood in front of me and said hop on my back.She carried me on her back for about 500 feet. Then she stopped and told me to hop off. She then squatted down and said sit on my shoulders.I then got on and she carried me for what it felt like a half-hour. She said I was light. I weigh 160 lbs and I am 5 foot 11. She weighs about the same and is 5 foot 10 .She said she liked carrying me and plans on doing it again.
