I have been into different places, local and international. I have stayed in different hotels and inns but I have never tried sleeping in metal building. When I went to Asian countries, all I have seen are houses made of wood or made of concretes. I still have not seen any difference in my country. Most houses here even rest houses in farm lots are made of wood and hollow blocks.
I want to visit some other places that have different houses, like Japan who had paper houses and like in Atlantic where in they had Igloos. Ohhh when will I be able to go to those places for a change.
