Sorry about the gaps, the wi-fi at my hotel stinks (I'm in Utah, teaching classes for Spacely Sprockets)
When Lovely Wife & I took our Route 66 trip we didn't make it to Santa Monica, just to Needles, CA. Here is the 66 Motel right off of 66. The sign is on 66, but the motel is about a block off the road. I'm not sure how much of it works, but I think the color scheme is pretty interesting. It is all pastel colors, very appropriate for California. Normally signs of this type are all primary colors and very bright, but Ca. does things differntly
Here is a shot of the motel. Click on the pics to look closer.
