I think I might have posted this last your. Oh well here goes. I was fishing for whithfish off of Garden today and like last year the whitefish will swim by and not even look at the baits I present to them. Some will come in pretty close but then they leave as quick as come in. I also see lots of whitefish in the back ground on my camera going by. It's not like I'm not seeing any to say they aren't biting because I am seeing lots of them. I tried throwing almost everything in my tackle at them but with no luck.
I have a freind that used to use a dead Perch minnow on a plain hook and a split shot about 16 inches up. Let the sinker lay on the bottom. I don't know what kind of float he used but had a lot of sucess this way. You may want to play with the leader length.
