The two-day Pru Boo Halloween event at the Prudential Center in Boston will merge with the Halloweentown event from Boston Medical Center to raise money for BMC's Kids Fund. Over 120,000 people are expected to attend the family-friendly event which will include activities like costume characters, games, dance parties, and trick-or-treating. Sponsorship opportunities ranging from $1,000 to $35,000 are available to support the event and Kids Fund, which helps over 25,000 low-income children in the Boston area each year.
