Robin,
I am not that far from Cree lake, if there were roads there it might be like a six hour drive but, looks like you have to fly in. Never heard of that book before, it's on my list now.
WalesWalker,
The Churchill must have been nice! Big Salmon would be a nice one too. I have talked of the Yukon and the Mackenzie but not this summer. So far I was thinking the assinaboine, coming out of jasper national park and/or Prince Albert park and visit grey owls cabin. also would like to head north to lake Athabasca. Asides for those I will be doing local trips such as the North Saskatchewan river, beaver river, Martineau river and lakeland provincial park.
