Tomorrow, at the Cathedral of St. John the Divine, is the 7th Annual Blessing of the Bikes. The The Very Reverend Dr James Kowalski will wish bikers from all walks of life - messenger, commuting, kids, you name it - a safe biking season. What's awesome is that bikers get to bring their bikes inside.
St. John the Divine is on Amsterdam at 110th Street. Another cool event to mark in the calendar is the Feast of St. Francis, when all the animals are blessed (see these pictures on Flickr). The Hungarian Pastry Shop is just a few blocks away, if you need a nosh.
