How bad was the boat traffic? I've seen some crazy things on that lake, been on it twice for the 4th of July and I probably don't ever want to do that again. only way I would get on that lake during a summer weekend would probably be on an aircraft carrier, I might feel safe then haha. All kidding aside fishing St. Clair will help you when you come back down here as far as getting a new mindset on where the fish can be. that lake has given me new insights and confidence on fishing offshore, especially during the summer months. Glad you had a great trip, next time try a week in mid May.
