Well, I put higher confidence in seed sources in bag weed in the 70s/80s than from any but a very few seed companies today. Where did the seed companies get their strains from and are they legit? Also where did those modern seed breeder genetics originate from? Mysteries galore. Like the source of the several dozen OG Kush strains out there calling themselves OG. The dealers in the 60s had far less to gain from where a bag of weed came from than seed peddlers today. And in the end, most Mexican weed was from Oaxaca, Guerrero, or Michaoacan and most Colombian was from the mountains (Santa Marta) or the northern Atlantic lowlands (bricked red/brown and gold). Some came in from west Colombia, which was green, and there was punta roja and punto rojo from the west mountains. Thai sticks were obviously from SE Asia, mainly Thailand. Black gooey ganja was from South India. No doubt about it. The hashish pressed into the Star of David was from... you guessed it! Israel. Bright green temple balls and fingers were from Nepal. Red and blonde hashish was from Lebanon.
As for memory, I do not need to recall the details. I wrote everything down then about the source weed when I added seeds to my land race seed collection sorted into envelopes and frozen in a plastic case. Date, price paid, where gotten, where said to be from, character of the buds and quality of the high, how seedy, and I rated the buzz factor. I also noted the germination %, how it grows and the dates grown for each seed packet over the years.
I also lived in Sandy Eggo in the later 1980s, on Mission Beach and in Del Cerro. I graduated from SDSU. The beach scene there and in LA was a lot different than the weed scene in NorCal at that time. Different worlds. I loved the surf music in PB though, and the beach. I do not miss the traffic, smog, and mob scene there through. I went back to Mission Beach a few years ago and it is all quiet and tame. Family friendly. They banned alcohol on Mission Beach and that was that. The party was over. It had moved up to Solana Beach and Encinitas then. Back in the day my brother was living out of his car on Cardiff Beach at the campground. That had been taken over by a surf camp for kids last time I was there. The waves were glowing at night on that trip though. No ono believes that either... even there and then. Bright green crashing waves. No LSD required.
