Great topic - reminded me of books we have that I could get out one at a time and enjoy while being stuck at home...
We've got a set of National Geographic books with titles like:
Scenic Highways, Hidden Corners, Rural America, Alaska's Magnificent Parklands, etc. They will be great to put on the coffee table and peruse. And yeah - they are pretty old - from the last century anyway. That might make them more fun.
And we also often pick up books from the visitor centers at National Parks - gotta get out the book we got last spring from Sleeping Bear Dunes.
