kansas
Having talked to Oracle and Dinah already--not to mention a Batman from after the one he knows--it's obvious to Hal Jordan that if he wants to get to know this world better, he will need to start with Kansas. In particular, the Kents' old farm, now owned by this 'Lucy Cooper', whoever she might be.
Hal was never out to the farm as much as other members of the JLA, but he remembers well enough where it was, and he's not surprised to find it in the same place in this world. Still, he opts to cruise around the area a bit first. Maybe he'll run into more people he knows.
And maybe he'll get used to the sight of Metropolis rising up from the plains of Kansas. Eventually.
