If a Vet lives in Albany, Or will an ambulance take him to Portland hospital. And if so, do they charge for it?

Not an ambulance, but medical transport , but you have to be a va patient, not just a veteran. Call the benefits office and they can help you.

I know a friend of mine had prescribed treatments and they paid for transport back and forth to his house because he lived out of town but if it's an emergency they all take him wherever they need to take him and the VA usually pays if he service-connected call the VA for more information
