My youngest, 7-year-old Ezra, is afraid of volcanoes. I don't know what image nested in his brain and hatched as fear, but for as long as I can remember, every time we visited a new place, he asked the following question:

"Are there volcanoes there?"

I've had to explain that there are no volcanoes in Philadelphia, the Poconos, the Jersey shore, Lego Land, Florida, Vermont, North Carolina or London.
