One must wonder what those diverse traditions are and exactly what holiday is referred to. Could it be, perchance, MLK's birthday, the 4th of July, New Year's Day, or surely not the birth of our Savior.
Diverse could mean perverse, as in homosexuals and their traditions handed down by satan.
New Haven, unfortunately, has slid into a sewer over the past 25 years and is today a valueless metro area.
For those poor souls who celebrate Christmas I would first of all not buy anything in New Haven and secondly I would plan to get the 'hell' out of that hole.
I used to go to school there, well over 25 years ago, in the '60s, and it was a run-down pit 'way back then as well.
