Bundle up for an evening of winter celebration, when Hudson's Warren Street overflows with music, dance, and costume to welcome the season on December 5. Businesses exhibit their best holiday window shows and invite festival-goers inside to begin their holiday shopping. Street-corner musicians will play everything from carols to jazz to African drumming. Horse-drawn carriage rides are offered up until the evening closes with fireworks at 8pm.
