Trader Joes is exactly the sort of "destination store" that would pull people into the city. Not only that, but Trader Joes prefers cheaper real estate in gutted older buildings.
I've got some contacts at CC, but given their current financial situation I wouldn't even suggest this to them.
So long as we're talking pie-in-the-sky, wouldn't it be nice for WTVR ("The First TV Station in the South") to move closer in on broad street and have some sort of museum/visitor center space with their studios. I won't go so far as to suggest a Today Show-type window onto Broad, since I'm a little afraid what we would see out the window during those 11:00 p.m. broadcasts.
