Supergirl #6 by Greg Rucka (2005)( the start to Karaās worst arc ever) had one cool idea before the arc gets completely derailed by Joe Kelly: Kara on a quest to find Argo City.
Supergirlās Family Vacation had her searching and finding Argo City not in ruins, but alive and thriving. Her people managed to find a way to push through after her dad sent her away and created a beautiful city 20+ years later.
