Why wouldnt a Vet go to school in state to begin with?

Majority of guys I knew who got out either went home, place of residency or
made their final duty station they place of residency already and usually had the correct time in
that city/state to qualify for in state tuition.

I guess I am playing devils advocate.

Im a vet and kept my residency in Colorado for my time in and took some classes on
the G.I. bill, stopped cuz I was working nights and taking care of my daughter at the time,
and had in state tuition.
