I remember my first introduction to Bigfoot. A documentary came out in the early 70s and was shown at my local theater. I remember thinking, "there's someone hairy and wild in my woods?" I went out after the movie day and put on about 4 jackets, 3 pairs of pants, huge winter gloves, a football helmet and went into the woods to make contact (afraid it might bite me).
I had no encounter, but I did want to see more, so I saw upcoming popular Bigfoot films that were coming out right and left at the time. The 70s really brought Bigfoot home for people for the first time. We didn't have VCRs and rarely did they replay episodes of shows that might have displayed the Patterson-Gimlin film. I was way into the 70s before I saw that film taken in the latter half of the 60s and in my mind, it took place in Washington State (I had it in my head that is where they all were from documentaries). When I actually saw one in California in the mid 80s, I had a hard time assimilating it since I believed they didn't live there.
Interestingly, if you watch one of the 70s documentaries (besides being rather dorky), they often interview witnesses that we no longer talk about and you hear stories you never heard before in modern times. It's quite enlightening.
