Near my house there is a place called Grosse Pointe Village. I have found the following nests:
Piplup
Magikarp
Wailmer
Sableye
Sudowoodo
Turtwig
Misdrevous
Snorunt
Sneasle
Swinub
There are lots of ice, dark, ghost and water at Grosse Pointe. Great location for beginning players looking for a jumpstart and what not.
