We did, and they were seriously awesome. A library inside of a BUS. We drove to Chicago to pick up my dad's new car, and on the way back we stopped at McDonalds, and this pulled up alongside the curb. I had completely forgotten about them until that very moment.
I was able to go inside. Of course it was a bit more updated since the last time I had been in one. They had DVD's and audio books, and other such things, but they did have a nice array of Nancy Drew on the shelf, so Claudia would have been happy. (No BSC that I could tell, though.)
