The first(?) will be focusing on Champ, the Lake Champlain monster. They're currently doing the filming up at the lake.
"In 2018 Small Town Monsters launches their first spinoff series with 'On the Trail of…'. A yearly, documentary miniseries that tells not just the fascinating history of America's rural monsters but also goes in search of them.
"Aleksandar Petakov will direct this miniseries focusing on Lake Champlain's famous monster."
The last doc I saw on Champ, which appeared a few years ago, was crap, but with Petakov and the STM crew, you can be this one will be good.
