A farm in Landenberg, PA, the Meadowset Farm and Apiary, has an annual openhouse/sheep shearing day. This year it'll be March 14th beginning around 10am. I've never been but my friend Reluctant Mango said it was a fun little event last year, with spinning demos, sheep shearing (obviously), and finished items for sale. And they shared some homemade lamb chili (yum!).
I think I'm there..... :)
