My 3 Regions
I CHOOSE: the interior lowlands because it has good soil, its kinda flat so it easy to get through, and has fresh water. The great plains because its flat and easy navigate through. and coastal plains because it has a good source of food.
It's a flat sand beach area with a good source of food (fishing).
It's a wet, low type area with very good soil, and lots of rivers, and lakes including the great lakes.
It's a flat, dry area with not that much water but easy to navigate through.
