National Ice Cream Day is Sunday, July 21 and you most definitely want to celebrate. But will you celebrate with something more exciting than Illinois' favorite ice cream flavor?

Pretty much every day, there's a 'National' holiday. Some of them are actual holidays when we don't have to go to work or school, and then there are others that don't really cause for a huge celebration BUT when we're talking about something as delicious as National Ice Cream Day, we totally need to honor the day!

Even though I swear I've seen other studies that has Illinois' top flavor as Blue Moon, this time around we're clocking in as boring with vanilla taking the number 1 spot.

I'd much rather have chocolate or rocky road! Or cookie dough, or cookies and cream or butter pecan or my top flavor of all time, Ben & Jerry's Chocolate Therapy.

What about you? Is vanilla ice cream really your favorite? Or is it just pretty good.
