March 14 = National Pi Day which is often treated as a pie day -- instead of getting a fruit pie or pizza pie, how about you make a chocolate pie
3rd week of March = American Chocolate Week -- I'm betting this is really a United States Chocolate Week but we casually use "American" even though it cold apply to anyone living in North, Central or South America.
March 24 = National Chocolate Covered Raisins Day -- I'm not a bit fan of raisins but I did note a new dark chocolate version of Raisinets that perhaps I'll try for you all
March 26 = National Make Up Your Own Holiday Day -- I want suggestions for this. Make them please and if it involves chocolate in a way that we don't all ready have a holiday for, your suggestion will be one we'll vote on as a group.
