I would do some dirty shit to get my hands on ANYTHING CLOSE to the real deal sour d, like AAAA+ sour.
I grew up in ny, and 15 years ago i was getting this sour that was outta control.
Then came this stuff called "piff" dark green frosty nugs, real funk smell that would fill the room, and the taste was like a yummy funky inhale but on the exhale it was completely different, allmost like a vegtable... like broccoli.
Piff aint a fucking strain and no one ever told me what it was and shit like that hurts my feelings.
