One of the nice things about OTR jobs is this, The job is on the road, where you live is where you live. We did have an o-o team that lived in Alaska. They commuted down from there(sometimes with the tractor sometimes not)
I have met a number of drivers from Puerto Rico, )they did not drive for KLLM) same thing just a long commute.
The Northeast has a huge population, and as a result lots of freight.This makes it easier to get home.
