I m not wedded to the neighborhood split I just thought that that was the way it was done The Boston neighborhoods are not very well defined in most cases To some extent that s a matter of people wanting to be in the classier neighborhood so over time the boundary migrates with the upscale neighborhood getting larger It certainly is not as well defined as the Manhattan splits for example Also while they are well defined by City Hall in order to issue neighborhood parking permits even this geo interested forty year resident can t draw them on a blank map I had to look up several as I was going over the classifications and I m sure that the average user won t know them And there are the seven above in more than one neighborhood Perhaps it would be clearer to do a straight alpha split A H and I Z gives approximately equal halves That also eliminates problem of sites that are in multiple neighborhhoods Jim
