This is sort of a cop out, I know.
I'm sending this from my phone, whereas normally I use my VERYFANCYCAMERA to document the beautiful weirdness of l.a's oddball buildings. But I'm en route to san francisco to play records for the young persons, and I left my VERYFANCYCAMERA at home.
Cos its big.
And I travel light.
Possibly as a result of deap seated psychological issues.
In any case: bob hope international airport. 99.9% of the people who fly in/out of los angeles use lax. But some of us try, whenever possible, to use bob hope (or burbank) airport. Why? Its tiny and provincial and feels more like flying in/out of duluth or sacramento or albany. plus, and most important: it has a giant weird mural of an old plane being pulled by winged horses (pegasus? Pegasii?).
So, here's a picture of the glamor that is bob hope international (I'm still not sure how it qualifies as 'international'…maybe a once a week flight to tijuana?) Airport.

Architecturally significant: possibly not. But its little and weird and possessed of a mural of pegasuses pulling an old timey plane. Which makes up for any inherent lack of architectural significance.
Thanks
