Much of downtown Boulder has been replaced in recent years by new construction in the form of red brick buildings.  Now we have a "financial district" where we once had a motley collection of older buildings and businesses.  None of this has really bothered me but today, when I read that Lolita's Market may be replaced by a newer 'energy efficient' building, a little "aarrgh" welled up in my throat.  
The building that is Lolita's dates back 130 years and has been a downtown market since 1979.  The developers promise to keep the history alive with a photo essay to show everybody what once was there.   Will that satisfy the basic need that people have for some sense of continuity?  I don't think it will.
