The lower French is a hard nut to crack for muskie, you really gotta fish it like a river opposed to a lake. I had one nice blow up after a week of fishing for them (Early morning and evenings only) other guys at camp boated 4, including a 54in giant. We'd have completely different stories for that week, although for me the scenery is enough to keep me coming back. I'm definitely not a hardcore muskie guy but I thought I put a decent effort in over 7 days. We did destroy the walleyes though, haven't had walleye fishing like that in a long time. We stayed at Bears Den, I'm sure you drove right past it on your way from Hartley Bay Marine.
