I would definately recomend trying the Soo. Early July should be when the Atlantics are in the rapids. Tough fishing so I've been told I've only fished there in May and Sept, but when you hook into one it'll be worth it. When I was fishing for Steelhead there in May 2000 I witnessed a guy hook a huge fish across the channel from me he held it up and it went from his hip to the ground ( and he was average height) I spoke to him in the parking lot and said boy that was a nice steelhead and he saud that it was an Atlantic salmon I had no idea that they got so big there. I don't know about you but I'd sooner catch one salmon than ten bass.
Oh ya they troll for them off of the Edison power plant too.
