If Season 7 is the last of the series, and Luke is deciding whether to move to NM to be near April, I hope Lorelai decides to go with him. She could sell her share of the DFI to Michel, and Luke could sell out to Kirk (he did run his own makeshift diner...) and L&L could open their own place, maybe a B&B, in New Mexico.

Strange to think of them leaving the Hollow, but who cares if the series is over?

If there's a season 8, then the quandry over whether to move could spill over into that.
