On a snowy day, a dinosaur-loving boy and his dog roam around imagining that snow-covered objects are buried dinosaurs. Cute.
The concept is fun and the cartoons range from the eye-rollingly lame to the run-into-the-other-room-brandishing-the-book hilarious. There are a lot of "typical" New Yorker cartoons, of course. It's well worth picking up and leafing through, though I don't think I'd read it more than once.
