“We had a terrific, intimate experience getting to see the Milk Carton Kids for their benefit show for the artists in residence program. We really enjoyed exploring the museum and all of the Halloween decorations, and look forward to visiting again and trying to track down more of the secret passages. Thanks as always for your hospitality and generosity!” — Benjamin Kunstman
