I'd personally probably go:
LA
ORD
ATL
NY
The distance to LA is longer, but the WX is better than ORD. It's probably a wash between LA and ORD. Neither is 1 day drivable from DFW, but ORD is closer.
Several flights run ANC-DFW-ATL with a single crew. This means if you would go with ATL as a base and DFW as a preferred port you'd frequently wind up getting dropped off in ATL vice DFW. Something to think about.
