Hi Kerr,
I follow the co.in OVT results very closely,and unfortunately it doesn't have true OVT with extention.
The reason it shows up when you search "co.in" is actually from people looking for Boone County Indiana (Boone Co In)...
Official state websites often are long such as [B]www.bccn.boone.in.us[/B] so it's extremely unlikely,but possible you might get a trickle of traffic from confused people.
I used to have DWD.in (41 OVT with EXT) which received traffic from people looking for dwd.in.gov.
Good luck with it.
