There is a Monday night dogfight out of B &B marina on the hiwassee and one out of Chester frost. Then a Thursday night one out of Harrison bay state park. There is also a Thursday nighter on nickajack. Usually an initial buy in of $30 a person. Then $15 a person after that. Typically from 6:30 to 9:30. 3 fish weigh in. The Harrison bay dogfight is definitely the biggest with usually 50+ boats. Hope this helps!
