The Great Lakes have often been referred to as inland seas.

If Sheila wanted to sell sea shells by the sea shore, to reach salt water from the cache, she would have to travel (fly):

590 miles to reach Hudson Bay

or

830 miles to reach the Atlantic

or

957 miles to reach the Gulf of Mexico

or

1840 miles to reach the Pacific.

Surely she’s successful selling sea shells lake side.
