In the fine spirit of giving thanks for the many blessings in our lives, the Massachusetts Attorney General’s Office is investigating whether supermarkets opened on Nov. 24 — Thankgiving Day — in violation of the Commonwealth’s long-standing Blue Laws prohibiting such crass commecialism (Christmas and New Year’s Day receive the same protection).  If such a law were in effect in my home state (Michigan), it would have prevented two last-minute trips to the store and made for one unhappy group of diners who much appreciated the home-made, deep dish apple pie that is the best around.  An AP story (here) discusses this important use of investigative resources.
