DeWine also announced a new quarantine policy for people traveling to Ohio from the United States' worst-affected regions: Alabama, Arizona, Florida, Georgia, Idaho, Mississippi, Nevada, South Carolina and Texas.
Anyone entering Ohio from those states must self-quarantine for 14 days upon arrival, regardless of whether they are an Ohio resident or a visitor.
Concerning the quarantine from southern states, I went to the Ohio State FAQ page. This is what is there. Apparently there will not be traffic stops to determine your destination. The governor has said this is only a recommendation. The state does not know if you are stopping in the state or simply passing through to get to another state.
This might play a role in your decision to attend a CubFest. We will not force you to stay.
