I got a few.
Empty movie theatre. It was my first job. We would close up and play a movie. Kick our feet up and pass around a JBD bong like it was a private showing.
Back of a cop car. My friends dad was a cop, and he had taken the company car home. They went on a date night and me and my buddy hotboxed the back of the car while his parents were gone.
Closed zoo. I wandered through a garden at a wedding reception and the garden was connected to the City Zoo. The gate was supposed to be closed and locked but it wasn’t. I wandered around smoking weed all by myself until I stumbled upon the tropical bird sanctuary. I accidentally woke them all up and they freaked the fuck out. Every bird in the zoo was squawking and a security guard came to see what was going on and kicked my ass out.
