On 322 in south Delaware County, they could have been trying to get to the Brandywine Museum to appreciate the Wyeth paintings there, or perhaps going a few more miles to Longwood Gardens, which has one of the largest pipe organs in the country, complete with a true 32' stop.
Or not.
P.S. There is a collection of N.C.Wyeth and Norman Rockwell paintings at the museum closest to home, the Polk Museum of Art; if you happen to be in central FL, it's worth the trip, and admission is free.
Been to the Brandywine Museum. It was years ago and I thought their Wyeth display was a little sparse.
