Hi, This looks like a great way for your trees to be of use and to meet those adorable goats who help rid our parks of invasive plants! Allegheny Goatscape will host two Christmas-tree donation events on Sat., Jan. 3 from 11 a.m. to 1 p.m. at Healcrest Farm and another on Jan. 17 from 10:30 a.m. to 12:30 p.m. at 447 Marshall Ave. on the North Side. Visitors will be able to meet the goats, sip Commonplace coffee and hot cocoa, and explore volunteering opportunities while the goats enjoy their Yuletide buffet.
