Is there anything interesting in between the two cities?
Nope. Pure
pampa, flatlands full of crops and some cows. Quite similar to the landscape you saw from Buenos Aires to Rosario but with less population density. The only "big" city between Rosario and Córdoba is Villa María (roughly 100,000 inhabitants), without any touristic or historic relevance.
