Americans love their pie, so much so that the American Pie Council created a day – today, Jan. 23 – to honor all things pie. Locally, Grand Traverse Pie Co. is offering a couple of ways to celebrate: Stop by GT Pie anytime today and get a free slice of Michigan fruit pie with purchase; follow GT Pie and Pure Michigan on Twitter, tweet them both your favorite type of pie (tweets must include the hashtag #puremichiganpie) and be eligible to win an entire pie – one will be given away every hour.
