remember the 1970s?
I am 50 now, worked in a Camera Store/Studio in Southwest Michigan in the 70s-80s.
Does not anyone here remember the supposed government spraying of farmers fields with Paraquat? At that time I heard on the radio that film developers such as Dektol and D-76 contained Hydroquinone, which could be used somehow to "detect" the presence of Paraquat, thus letting the "hippies" know if their pot had been contaminated. I remember the quote "check your pot for Paraquat".
We actually had a few people come in to the store that were not regular customers, only buying powdered developer for a week or two.
