One internet cliche I never tire of is the "vintage postcard" site. I know that after a while it's hard to tell the Route 66 roadside motels from the 19th-century faux-classical state buildings, but that doesn't stop me from picking a few I like and ogling them admiringly for as long as I feel like. I found CardCow yesterday while Googling for something else, and I've kept the page open in the background ever since, waiting for a good opportunity to blog about it.
