Now that's a gooder. I have no problem sharing lakes as that is sort of the same thing as sharing a snowmobiling area. The honey holes might be a little different!
That was at Otter Lake (Thompson's Resort in Missinipe, SK) which is 80 km north of Lac LaRonge. It is on the road so the lake generally has been over fished. They have lots of out-posts to fly to where the fishing is spectacular but it is expensive. This trip was not too bad; seven of us, for two nights in a well equipped cabin on the lake, 1/2 day with a guide and a two day pontoon boat rental for $1500.
