Was Thanksgiving a Jewish Holiday?‪?‬ Getting BIBLACHOL

Thanksgiving is upon us yet again folks! Usually thought of as a simply secular holiday to be enjoyed by Americans regardless of faith, however I thought I'd dive into a bit of a history of the holiday and discuss my own crackpot theory: Was Thanksgiving a Jewish Holiday??
We also eat some Haagen-Dazs Spirit flavored Ice Cream - of course I grabbed the Bourbon flavored one! It's really great stuff, and you might want to grab a pint before having to see your in-laws for the big meal!
Happy Thanksgiving Everyone!
