Mine would most likely be a microcosm of the shire. I would've said just Hobbiton, but running north and south on the border of my neighborhood is a forest - the old forest of course! I live in New York, and the land is full of hills and every house could be bag end because of the enormous trees overhanging!
Ive even mapped it out in my mind, and whenever i leave somewhere form my neighborhood i have different areas i associate with the path to rivendell. Its fun!!
