At my high school last year during my Freshman year, the school district's lunch departement would drive in with a huge truck to deliver food just before lunch. Well, before I had heard em' blasting "From The Cradle To Enslave" by Cradle Of Filth while they were driving through the school. It was hilarious, but too bad it was during class time so not many people heard it.
A few months later, the dude who drove that truck ran into me while I was getting a soda out of the soda machines. I had a Dimmu Borgir shirt on and he was telling me how much of a black metal fan he was.
Eh.. Aside from that, I never heard anyone play Opeth or any metal..
Oh wait no, I heard some guy blasting Lamb Of God before.. But I dont really like that band..
