Neewollah - Independence, Kansas
Neewollah (which is Halloween spelled backwards) began in Independence, Kansas in 1919 to provide positive activities for young people in place of Halloween pranks. Today Neewollah is an 8-10 day celebration which includes 3 parades, a chili cook off, a musical & queen's pageant, carnival, concerts, arts and crafts show, Great Pumpkin contest and more. The most interesting activities (to me) are Saturday's Grand Parade and the marching band competition.
The Neewollah Grand Parade is on the final weekend of the event. People start setting their chairs along the parade route hours in advance and by the start of the parade the crowd along the route is 5 deep. The parade runs nearly 2 hours. Since there is also a band competition in the afternoon, marching bands from 3 states participate. The only thing which could make the parade better is more use of the Halloween theme.
20 of the 26 bands in the 2011 Grand Parade participated in the Marching Band Festival and it ran most of the last Saturday afternoon.
