My ideal city would be at the sea. There would be many people, famous people, a bit like Vegas. There would be a lot of shops, all different. there will a lot of Port, boats, famous monuments that every the world would come to visit. People would be happy. There would be no fighting, kidnappings or political problems. A kind of paradise in land.

Gone are the major downtown pedestrian crossings in the streets, a clean city first. The mayor had good ideas to renovate the city, decorate, embellish, to advertise ... My ideal city would be modern. There would be many engineers innovate technology. This city is popular because it is modern but also thanks to these monuments is older neighborhoods, homes and farms in the 18th century...
I wish there were a lot of animals. Strong “infrastructures” and modern. Associations, hospitals, nursing homes, restaurants, a library, a post office, a butcher, a baker, a shopping center, schools of all levels (nursery, kindergarten, primary school, high school, college ...).
And the climate is tropical. 

a part quelque petites faute de sens c'est parfait !
