Should Minnesota give land to Canada?

The Northwest Angle is known to local residents, people who love to fish - the region is famous for its walleye - and geography buffs.

It is accessible by land only through the Canadian province.

Now, someone has anonymously launched a petition urging the US to hand the land over to its northern neighbours.

"Make America great by correcting this critical survey error," states the petition posted on 30 December on the White House "We the People" site, which allows citizens to petition Congress on issues that matter to them.

The petition is titled "Give Canada back the Northwest Angle located in Manitoba".

The nub of Minnesota state is roughly 123 square miles (318 square km) and is farther north than any other part of the contiguous United States.

Living above the 49th parallel, Angleites - as local residents are known - are the northernmost American citizens, barring Alaskans. It can be reached by driving through Canada or by boat across the Lake of the Woods.
