Cincinnati Transit Historical Association
The Cincinnati Transit Historical Association is a non-profit organization dedicated to preserving transit information, photographs, ephemera and memorabilia relating primarily to the Ohio, Kentucky and Indiana region. The Association offers monthly programs, normally consisting of slides and movies about present and past transit systems, sponsors periodic fan trips to transit properties, publishes a monthly newsletter, and has speakers available to present their popular slide show "A Nostalgic Trip Through Transit History." CTHA also maintains a fleet of restored historic buses which are regularly featured in car shows, parades, and other public and transit-industry functions.
