It was a crowded day at Tri-County Animal Shelter, as Tri-County and Tyson personnel, along with county officials, volunteers and plenty of dogs and cats, got together for another free adoption day event.  At one point near mid-day Saturday, cars were parked on both sides of the driveway leading from Ky. 90 to the shelter, as people took advantage of the opportunity to choose their newest furry family member.
