Continuing through January 26 at Butter Bakery, Royal Grounds Coffee, and Dunn Brothers, Linden Hills! facebook.com/events/508133723486639  ‘Waves of Thankfulness' is a FREE postcard campaign to close out 2020 and bring in 2021 with a flood of thank you cards to local hospitals, nursing homes, and clinics...simply to thank each worker for their part in keeping our community healthy this year. You can send your own postcard to any clinic or healthcare worker you know, or pick up one of ours…
