Flash, welcome to FM!
I asked a coworker this morning about Cass for you. He has a cabin there and fishes it weekly year round.
As far as colors go, he said natural colors. Gold, silver, browns, oranges as well as glow green are the best in that order. Reds, chartreuse and red/pink glows are lowest on the list.
Obviously transition areas tend to be the best locations. Deep vs shallow tends to be day to day season long.
Hope this helps some.
Had a CO come out to our shack two years ago on a pretty cold night, just as we were sitting down for dinner, & that SOB just stood in the doorway, left the door wide open as he checked all of our licenses... all the heat in the house GONE, our food went cold, give our licenses back, then on to the next shack--- No smile, no nothing, guy had zero empathy or consideration for anything it seemed.
Its basically the golden rule though> just treat others the way you want to be treated. Just don't be a dick.
