25/M - I am looking to move to eastern TN. Very likely Nashville or Knoxville. Which city I end up with depends on job opportunity I am best presented with.

I am from the middle of nowhere PA and cannot wait to have a night life either way. I have 1 girl lined up as a plate in Knoxville, but otherwise have not sure the best way to break into new social circles. Some people I will become acquainted with by pursuing my hobbies, but never had the ability to go to clubs/bars/etc.

What is my best option for new social circles via night life in Nashville or Knoxville TN?
