Well, here's the best I could do at capturing what I think may possibly, but not unequivocally, and yet potentially...my first actual plume sighting.

This was on a Camacho Triple Maduro that I'd had in the humi for about 2 years, and it had a fine, sparkly dusting of crystals all over it. It almost looked like glitter. Smoked great and whatever it was, it wasn't mold. That's my story anyway.
