While some may find this very hard to believe, there's a very small, very wealthy town called Gladwyne in Lower Merion Township, Pa where an acre of land goes for in the neighborhood of $1,400,000. That's no lie! People in that area often buy a million dollar home, have it razed, then have a larger more expensive one built!
I live only a mile and a half from there. What a difference that little bit of distance makes.
