It was actually PTA's Inherent Vice film that made me want to read Pynchon in the first place, this book trailer (narrated by Pynchon himself!) sold me on it.
I appreciate the advice, I wanted to start with something that wasn't Inherent Vice since the movie is still fresh in my head, but I wasn't sure where to. I think The Crying of Lot 49 is gonna be it. Thanks!
