How do you keep a car load of boys happy on a 28-day road trip?My answer is: BOOKS. Lots and lots of books.I have been reviewing the books that got us through our summer vacation, and I almost forgot TRAINS.My kids are visual kids, and DK Eyewitness books just feed the information into their visual brains. Each two-page spread holds lots of photogrpahs and text blurbs -- not a daunting amount of reading, by any means. This text has a British flavour. My book came with a poster and a CD of clip art -- never looked at the clip art, but the poster is cool.I liked this book for a road trip, because if you are waiting in a retaurant for the food to come, this is the kind of book you can read a little of this, a little of that -- anybody can pick it up and find something interesting.I like the nice big size of the book, and apparently it is indestructible -- still in great shape despite HOURS (days) of engrossed reading.
