It's likely you've had a few 'strains' here and there. It's just generally herb get's passed down between so many ppl, they no longer know the strain, or where it came from.I might get stoned for saying so (lol puns) but I've never smoked a specified strain. I've always just bought whatever my dealer at that time had. It's simply "great" or "decent" bud.
Jesus, I can't wait to live in a recreation state.
