My son's obsession for tractors...

As you may know, Wolfie loves a lot of engines: trains, trucks, cars, construction machinery and... tractors. He loves tractors. He has tractor toys, he loves watching real tractors when we are on the countryside, he is obsessed by them. So much so, in fact, that at his last visit at the local library, he asked (loudly) his mother to borrow Tractors of the World. The book you see on the picture. I knew you could write books on anything, I never thought such book could interest a little boy who is not even three yet. The librarian was not sure borrowing this book was such a great idea, but my son was adamant that he wanted this one and no other. And he really loves it. He now can tell the difference between a new tractor and an old tractor. I just wish I could share his enthusiasm.
