yo NewPhone - i had bags like that almost 1 month ago, from father west than i usually go, a spot right off lake st (i hope that's allowed - its not that descriptive).
same looking black bag, not solid black, but almost translucent, bags were so full i though they may have been dubs, but i paid for saws and kid didn't argue, and yeah, they fucked me UP. i was very pleased.
never went back to get more, cause i don't like that area, too hot, but i went that day cause my reliable spots weren't open, other spots were out but wouldn't serve me (said they only sold weed), and i used to score out there last summer when there was less heat.
it was a spot that sold capsules last summer, but the caps weren't over sized and that strong like those black bags were.
Glad to see they might still be out there and someone else is enjoying them too.
