Adults, get your Halloween fun in on Friday, October 13, from 6-8 p.m., with a Murder Mystery Night! "Offed at the Races" is a horse race themed interactive event where attendees ARE the actors, and dress up to participate as characters or sleuths. This is a fun evening of theatrical entertainment as participants play a role and work together to discover the culprit.
