For many years urban development in the US and Canada have been moving out of cities and into suburbs.

Small towns with farms and open space make up the rural fringe.
These are connected by roadways and highways

Some people see the growth as a sign of progress others see it as harmful urban spread.

Land in rural areas are less to buy and building materials are cheaper.
Pro-growth people say there are benefits to growth, others think it's too much
