Every year the Saturday or two before Halloween the streets of the Village are shut down to auto traffic for the day. Tons of vendors of all kinds come out to sell and share their wares. Lots of artists (many local), lots of store owners, and food vendors line the streets from early morning until about 4:00pm. There's usually a costume parade in the morning for kids and many kids leave them on throughout the day. There's also a pumpkin carving contest and a Scarecrow decorating contest which visitors can vote on at the park. Usually a group will also be at that location providing fingerprinting services for children. The Police department hands out trick or treating bags, many businesses give out samples of things. It's just a fun day, a good way to do some early holiday shopping, and to get some very unique artistic items that you won't find anywhere else.
Every 4th July there is a parade and festival in the city park. There is a talent competition and lots of booths for various organizations. You have to do it at least once to get that old hometown feel that is missing from modern life. The last time I went there was an Uncle Sam on stilts and 7-year old ballerinas dancing through the park. To top off the day there is a spectacular fireworks show at the colleges which you can pay to see or do like the locals do and lay a blanket on the lawn of a nearby college.
