In this episode a bear invades the Heck's camp site. They are camping in Indiana and Indiana does not have bears. To make it worse, it wasn't a black bear which would be more likely to be in the surrounding regions of Indiana, but it was a Brown bear that only exists in the Northern Rockies.
When the Heck's are camping and encounter a bear, well there are no actual bears in Indiana. There was one that swam across the Ohio River from Kentucky into Indiana back around 2015 or 2016. We do not have bears in Indiana.
There are no known cases of bears being attracted to menstruating women.
