One place I've spent a massive amount of time browsing is the Library of Congress Digital Archives. It almost sounds smart to spend that much time in a library, even if it's only virtually!
The archives are full of old photos free of copy right restrictions (for the most part.) Combine that with some Flikr inspiration found in pennylrichardsca's photostream and suddenly I've got a nearly instant personalized Father's Day gift.
Here's the concoction:
This picture from the digital archives, which I believe might
be the original pagoda at the track (or at least one like it.)
This gift for my dad.
(I love the way the guy in the front is eye-ing that hot ride!)
