If it didn't put me so far away from my family I'd consider Boston since my brother-in-law + niece/nephew live there, but my daughter is much less attached to them than my mother and grandparents so it makes sense to stay close (at least PDX and SEA both have nonstop flights available to BOS, makes it much less painful to visit than the BOI-DEN-BOS legs with Southwest).
Boise drivers are terrible as of late too, my wife hates getting in the car - just glad she is a stay-at-home mom so she doesn’t need to deal with I84 or the east-west arterials at rush hour :/
VRT is finally looking at expanding their hours and service area but it’s going to take a decade or more to even get to a point where they can invest in a rail line from Caldwell to Boise - I can’t wait that long, traffic is bad enough and the lane increases ACHD has been working on aren’t going to cut it. Pine Ave from Meridian Rd to Locust Grove is going to four lanes and it’s going to get clogged right back up.
