nice one
good job
How I did it: Met someone who liked being outdoors and wanted to while away a night with me alone on some grass with the sky. Later we started using a sleeping bag and just collapsed onto it together after a long day of work on a night shift and spent time outdoors through midnight and the sunrise. We always loved to stare at the sky and stars.
Lessons & tips: Find someone who wants to do it so you can both enjoy yourselves.
