Drive-throughs should never be allowed in urban places.

I'd preserve a lot of the urban-format old stuff. But in a city with growth pressures, I'd say that outside key historic districts and the best buildings, it's generally ok to redevelop if the replacement is a lot larger than what was there.

As for mid-century buildings, I'd be very limited in what's worth saving. This is a fundamental disconnect between much of the public and preservationists...for many of us, preservation is about pre-war styles and well-executed urbanity, not about preserving "examples," and we don't have as much affinity for midcentury styles.
