In all of my thinking about McMansions, I have not considered this:
Certain neighborhoods just do Halloween better, drawing folks from ho-hum suburbs because the McMansion community three hidden-oaks-fox-glens over is the place to be.
In this consideration of social class and who is welcome to trick-or-treat in which neighborhoods, this might just be a throwaway example. Perhaps McMansions just quickly refers to homeowners with means.
But, it does raise a possible question: is Halloween celebrated in particular and better ways among McMansion owners? How would this be measured: more enthusiasm for the holiday? More and bigger decorations? Specific candy handed out? Lots of children on relatively quiet streets on Halloween?
I am guessing there are at least plenty of folk theories out there on what neighborhoods – in the abstract and specific locations within communities – are best at Halloween. I am not sure McMansion-lands would necessarily come out on top but they have some qualities that suggest they could be in the running.
