Paul,
I've had the pleasure of fishing with Bob Brunner and Art Ferguson (not at the same time ;-))). They are both top flight guides whom I'd recommend very highly.
Art is a bass guide who knows the lake very well and can teach you a great deal about how to fish st clair. He is a fine sportsman, too. Case in point: on the way back to the Metro launch Art spotted a mallard drake in the canal apparently in distress. He motored over, saw that the poor duck had become tangled in a mass of discarded monofilament, captured the duck using a towel, freed the animal from the mono, and set him back into the water, none the worse for wear. The man cares.
Bob is an all-fish guide who specializes in musky. He haunts Anchor Bay and knows it unbelievably well. Case in point: launching in my boat out of Selfridge early, he simply said, "Head into the sun." I did so. We crossed the bay and were headed in the general direction of the north channel. He made a couple of very minor heading adjustments along the way. He then said, "Stop." I did so. Bob turned the boat southward and, as if by magic, the most beautiful series of weedbeds appeared before me. There were fish in those beds, Paul, and I don't mean junior leaguers, either.
You can't go wrong with Art or Bob.
Mike
