We camped on both islands and mainland. In all the trips I have been up there I have never seen any bears or any sign of bears. Although I have heard others encountering them. I don't think I have ever hung my food either. So much of the area is primitive camping with very little use so I don't know that bears are associating camping kayakers with food. Maybe around the Rossport area and closer to Silver Islet.
If you do the Silver Islet to Rossport trip which I reccomend, you should plan at least 5 days to do it. 6 days is even better. It can be done in a hurry in 4 days but what fun is that. Keep in mind I know of one trip that only made it half the distance. They were wind bound for 3 days! That was in August, not in the fall. They never even made the full trip. Skilled leaders etc.
If you have some maps you should call me. I can go through some of the cool stuff as you are looking at the maps.
How do I contact you without broadcasting my email address all over the internet. Can you send me a pvt message from this board?
Never tired of talking about sea kayaking so get in touch with me.
