You guys always have such awesome suggestions so I thought i would ask.....DS8 has been a map freak for as long as I can remember - we have baskets and baskets of maps. he will sit and look through maps and be completely happy. Right now he is watching a video on the Chicago Metro and has gone online to look for a map of another system. Two of the best books we ever got for him are called Transit Maps of the World and his all time favorite book in the world....national geographic Concise Atlas of the world - the poor book is tattered it has been poured through SO much

Would love to know if there are others out there with map fanatics and if you have any book recommendations?
