More keeping the kids busy while dining out or waiting in line

I love these Little Dover books.  At about 4x5 inches, they are small enough that I can keep a few in my purse as a surprise for impromptu meals at a restaurant or waiting in line or even waiting at the doctor's office.  They are hard to find.  I have seen a rack of them at Cracker Barrel.  They are on Amazon for only 1.35! They ship for free with a 25.00 purchase.  Once you are on Amazon look around, there are many titles to choose from.
