OK, here goes. One of the top planning blunders has to be the wholesale destruction of neighborhoods that passed for urban renewal in
the 1950s and 60s. The most notable case around here is the West End. What a loss.
In terms of "festival marketplaces", or whatever the buzzword is, I don't find them particularly offensive and see them as a good way of making historic buildings valuable. As a Boston native I can't say I go to Quincy Market every day, but I don't avoid it either. I'd rather go there on a sunny day than the mall. Generally I like it, even though it has become full of chains.
