Take a horse drawn carriage around the square in Downtown Mt. Vernon for only $5 per person. For more information and FAQ find us on FB (King City Property Brokers). Profit from the event will be donated to our local CASA chapter. CASA is a national association that supports and promotes court-appointed advocates for abused or neglected children. CASA advocates are volunteers from the community who complete training that has been provided by a state or local CASA office. Donations beyond your ticket price will be accepted and are sincerely appreciated.
