On this day in 1374, one of the biggest outbreaks of St. John's Dance began in Aachen, Germany, before spreading to many other places in Europe. St. John's Dance involves groups of people, sometimes thousands, dancing eratically. It has never been well understood. Religious cults? "Mass psychogenic illness" (rapid spread of signs and symptoms in a social group with no known organic cause)? It occurred primarily in Europe in from the 14th to 17th centuries. Today I rode back to Burbank to pick up my van after the shop installed a hitch receiver for the bike rack. I felt strong through the whole ride. My fastest time from up San Vicente from Wilshire, and up the steep part of Sepulveda to Mulholland. The bike infrastructure is surprisingly good through the Valley, from Sherman Oaks to Sun Valley. Bike lanes most of the way, even if the quality of the pavement is sometimes quite poor. Only the last stretch, through the bit of Burbank with a big commercial sign that says, "Dump, Turn Right," was really unpleasant. And now I have a van with a bike rack! What an improvement!
