WHY I'VE NEVER SEEN IT
I had never heard of The Monster of Piedras Blancas; shame on me, I know. Even when I began hearing buzz about its release on Blu-ray (over two years ago), it was always in the context of "living in a day and age when even The Monster of Piedras Blancas is available on Blu-ray." That wasn't exactly a strong endorsement...
WHY I BOUGHT IT
...however, there was enough of that buzz, plus subsequent talk about how good the movie looked on the transfer, that I bought it soon after its release. It was actually on the bottom of my stack, which I flipped for the Countdown so that I'd begin watching the movies I purchased longest ago, first.
