Closest place to see penguins in person?

Edit-Just wanted to thank you all for the help. I’ve gotten my answers and then some. I really appreciate the feedback and personal experiences.

I live near Murfreesboro, where would be the closest place to go to see penguins in person? My fiancee loves them and has always wanted to see them in person. We are willing to travel as long as it isn't terribly far away(8 hours or less if possible). She doesn't know that I'm planning on taking her.
