Hamilton Heights has never been faced with making this decision. Conference changes were always due to multiple teams leaving. In the case of the Mid-Indiana, 4 of the 8 teams left in the same year because they could not compete. Including your beloved Maconaquah.
If 4 teams decide to leave the Sagamore, it most likely will die. It happened to the Range Line and the Mid-Indiana, possibly others in the State such as the MWC.
