Now -- our Geo Quiz today is a domestic one. We're looking for a city in Michigan.

Its nicknames include -- "Lumbertown" -- "Lumber Queen of the World" and "The Beer Tent Capital of the World"

Hmmmmm.

The actual name of this city means "marshy river or swamp" in the Ottawa Native American language.

"Lumbertown"

It's nestled along the banks of Lake Michigan and has a population of about 40,000.

Two of the residents of this city are about to start a project to reduce their carbon footprint.

They're being helped by a visitor from the BBC -- which co-produces our program. We'll catch up with them -- and name the city -- here...
