Your mission

City Mouse and Country Mouse are cousins, and they want to share a picnic. The basket is locked five ways. A COMMUNITY is a place where people live, work, and help each other. An URBAN community is a city, with lots of people and tall buildings. A RURAL community is out in the country, with farms and open land. A SUBURBAN community is in between, with houses and yards near a city.
