South of Portland is the evergreen air and space museum. They have the spruce goose in there, it's huge. The water park next door has an old 747 mounted on the roof, and I'd the start of 6 water slides.

That place is cool! Such a weird spot to put such famous flying craft but damned if it isn’t worth the drive.

Evergreen Air’s empire was/is based in McMinnville.

According to Wikipedia (https://en.wikipedia.org/wiki/Boeing_Everett_Factory#Current...), they are left with just the 767 (currently only available as a cargo or military tanker plane) and 777. 787 production was moved completely to the (non-unionized and reputedly lower-quality) South Carolina plant in 2021.

When I went through 20 years ago, it laid claim to “largest building in the world by volume.”

Not sure if it’s retained that title, but the inside is just insanely vast.

I knew a couple of people that had old bicycles from that plant. I'd love to own a Boeing bike.

This antique store had one on the floor, at least a few weeks ago.

Still is, according to wikipedia: https://en.wikipedia.org/wiki/List_of_largest_buildings

Amazing to me that a building over half a century old is still the largest in the world.

If I recall correctly, that building was so vast that they had trouble controlling the weather inside on a few occasions. Trouble as in, clouds were forming and rain was falling.

May that's just myth, but I like that myth enough to not google it.

They claimed this when I visited in 2019 as well.

I went in that tour about 5 years ago. It was fun. Would recommend.
