From Near Dark. Located in a town in Oklahoma: https://www.chicagotribune.com/news/ct-xpm-1987-10-02-8703140702-story.html

Home of a family targeted by creatures that while not explicitly stated as such were clearly vampires. While the vampire group was nomadic, this residence is notable because

after Mae, one of the vampires turns Caleb Colton into a vampire, a blood transfusion is complete there that reverts Caleb back to human. Subsequently Mae is turned human there through the same means.

No First Nations characters so probably not to the east where much of the region is Reservations. Probably to the west quite a ways away from Oklahoma City.
