Strange! It never occurred to me to have my hardwood laid any other way than perpendicular to where you enter the front door. I so specified when ordering what I wanted done and not a soul tried to persuade me otherwise.
Maybe it's because in my house in St. Louis (where I lived some 42 years) that's the way the wood was laid down.
Whatever, I am mightily pleased with my floors, and guests usually comment favorably!
