Kin-Yoobi Con is only a one day convention. While it is only one day, this will be its 8th year, so expect a good turn out.
Kin-Yoobi focuses on attendee interaction. Most of the events are gaming, gaming tournaments and other competitions. Dealers / vendors are open all day long for the event. If you are in the area go check it out. Small con, but worth the visit.
