Cars and Trucks and Things That Go by Richard Scary
I found this book at the swap meet a couple of months ago. I kept trying to get Lil'D to want to read it, but he always skipped it. I finally talked him into it. We have read through the entire book once. It took us two nights. Now it's all about who can find Goldbug first. Lil'D has memorized where he is on most of the pages. Lil'D says things like:
"Goldbug is really good at hiding."
"Where is that Goldbug?"
