This is simple. Don't be an a$$. If it's foggy, slow it down and turn your lights on. Always manage your wake, but that being said, if you are one of us with a bass boat, remember that it's better to slow it down and throw a bigger wake than to be on plane and kill someone due to lack of visibility. Non-motorized craft always have the right of way over motorized craft. Pass on the left. Stay to the right when motoring up or down lake. Slow down when entering skinny water clogged with boats. Watch for fishermen. Upper Taneycomo is for fishermen, not pleasure boaters. In the summer, particularly on the weekend when the upper lake is crowded with boats, watch your speed. There is no need to go 40 MPH above Lilley's. In fact, I'd be fine with a 30 MPH speed limit above Lilley's from May to September.
I, too, have seen certain guides engage in disrespectful behavior. Best solution I've found is to hook up a couple nice fish right in front of their clients while they express their displeasure toward you.
CAN'T WE ALL JUST GET ALONG?!
