We are vacationing in Oregon and was planning to visit the 11th of November, what will my husband need to bring to show he is a vet?

Show him your card. I used my canadian one. He wont be disappointed. Plan for a full day maybe a day and a half.

A copy of DD214, or if your drivers licence has the Vet ID on it that will work.

I used my dd 214. There is an additional $25 charge to go INSIDE the Spruce Goose besides the $25? museum admission. But if it's a slow day you can stay inside quite awhile.
