Yeah, hear of quite a few huge fish being spotted on electronics up at Jefferson. Last year, please forgive me, but last year we took home a 28 incher mack. I caught several in the 18" to 20" range there too. Was only there a few times though (I think it was like only twice). I'll maybe go up again this year, but my main fish to target are just a few of those in the 18" to 20" range... And yes, the smaller macks I caught there the previous year were all quite skinny too.
Good luck out there,
