In the next installment of our series Why didn’t I go there?, The Why co-host Shai Ben-Yaacov and his 10-year-old son Gil take a virtual tour of the time capsule that is the Mercer Museum in Doylestown. Their guide is the museum’s Cory Amsler who introduces us to the 19th century Penn archaeologist who was not just fascinated by ancient artifacts, but also had a passion for collecting the everyday stuff of his own time, from tools to … a vampire killing kit?
