Sometimes a bad idea is just so obvious: MOM organic grocery on New York Avenue NE

While the old Hechts Warehouse is an awesome art deco building, it's not well placed within the city in terms of being proximate to activity centers and neighborhoods.
So making it a retail center seems like a big stretch to me, as it will require car trips for virtually every customer. While plenty of people in DC drive, they are more accustomed to traveling west and north to shop, not east.
I can't see the MOM organic grocery store making a success of the location as what the store carries isn't so special--especially since so many of DC's highest income neighborhoods are served by Whole Foods stores (DC has four Whole Foods stores in the northwest quadrant, two on the way in Capitol Hill and on H Street, and two stores in Montgomery County are located just over the DC line), which carry the same type of merchandise, but more of it, and comparatively speaking, more cheaply.
