Join PCEI staff and board members to celebrate winter and the end of 2023 in the Thomas O. Brown Learning Greenhouse to enjoy tapas, wine and hot cider, live music, a silent auction, crafts (you’ll go home with tokens of the holiday season that will make lovely gifts) and great company. At 4 p.m., join — or just watch — the Palouse Roots Nature School-led spiral walk in the Nancy Taylor Pavilion. All end-of-the-year donations are appreciated, and a generous local donor will match gifts up to a total of $3,700 (for 37 years of PCEI). You donate at the soirée or at pcei.org/donate.
