My FIRST episode of TAR was Season 13, Episode 5. My family and I were flipping through the channels and we saw a floating village. My mom watched parts of the earlier seasons (Seasons 1-4) so she was familiar with the show. I saw Angkor Wat and was HOOKED.
My first FULL Season was TAR14. I didn't watch the first few episodes of TAR13 until a few years back, when I watched almost every season via YouTube. Sadly, most of the episodes are gone now due to Copyright.
