We were able to take advantage of our Gilbert House pass and get into the Evergreen Aviation Museum for free. Lucky for us, we had an experienced tour guide :-). Jaycoby has been to the museum once or twice when he's been at his dad's house, so he was really excited to show us around. He even sported his OSU sweatband for the job.
We only had an hour to check it out, and Jaycoby was literally running from exhibit-to-exhibit, so we'll have to go another time to really take it all in.
