Any other time of the year I would agree with apple pie...but Thanksgiving is sacred. Pumpkin Pie rules the roost.
The great thing about having a Canadian mom and an American dad is I get to celebrate both Thanksgivings.
Cool Whip, though? Eww. Say no to trans fat. Real whipped cream is soooo easy to make and so much tastier.
Don't get me wrong, I love apple pie. But, the question was about Thanksgiving. Pumkin is so autumn. While you can get pumkin pie out of season, I most associate it with fall and Thanksgiving. Although apple is also a fall fruit, you can get it anywhere, anytime.
