BF/GF IN TROUBLE!!! Is there a beach in Indiana that is aprox 2 hrs from Berwyn, IL? If you don't know, do you know how to find out?

Long story short, my girlfriend came down to Champaign (2.5 hrs from Berwyn) and her parents found out she is not spending the night at her friend’s house. She said they went to a beach in Indiana. Now we just need an ACTUAL beach that is about 2 hrs from Berwyn.

Thank you so much for any help!!!
