I have been to some really really good saltwater baitshops and also some very very bad baitshops ( based on knowledge not supplies)... I think my favorite baitshops that I have been to are small shops in florida right on the ICW, thier knowledge seem to be great and definatley didn't do the classic " that lure is working real well" and its $40, I liked these baitshops especially because the guys who owned them fished basically every day after shop hours and sometimes before...
Just a few months ago I was at the Cape Cod Canal and we went into a baitshop... After looking around and what not we asked the man working how the fishing was and what they were hitting, he said "You gotta match the bait".... Thanks for the tip! LOL!
A week later we went to the same shop and a different man was working there, it appeared to be the father of the man from the week before. We asked the same thing and he said " Oh with the tide going towards the west end blah blah blah, the fish should be between 264 and 275" (The telephone poles that go alon the canal are numbered). So this guy pretty much gave us an exact spot at where these fish would be... After arriving there we hooked up with 3 keepers, this guy definatley knew what he was talking about....
