CIRROPS is a local group of model railroaders who are working with individual layout owners and individuals looking to do operation even if they don't have a layout. This group has been in existence a number of years and has hosted invitational events every two years, in rotation with Cincinnati (SWOOPS), Fort Wayne (3ROPS), and Southeast Michigan (SEMICHOPS).
