Up along is a term used here for anything or anyone that is not here.
Up along can be anywhere from Nova Scotia to British Columbia. It only matters that is is not here.
Jim's gone up along for a spell. [Jim has gone somewhere that's not here for a while. Poor feller.]
Susan is from up along. [Susan is from a place that's not here. Poor scrap.]
We always feel sad for people who are gone up along, or are from up along. They aren't here. And that's a terrible, terrible thing. We're always sure they're up along, pining away for home. And if they aren't from here? Sure once they get here, we know they wish they were from anywhere but up along.
