I was too. Nicole is probably my favorite person on this season because her attitude is great, but letting that salmon go shows that she's living in the now not planning ahead for a long term stay. It doesn't surprise me that she's good with the plants. Many people here learn wild edibles and NW Oregon isn't that different than VI.
Forgive me if this has been discussed before, I'm new to this show and this series thread on the forum. Jose has mentioned it several times and I believe it was also mentioned by Alan last season that you have to move past surviving and look at this as wilderness living. I live in the PNW and have camped on the Olympic Peninsula and VI, it is during November as harsh at it is being shown. Many of the people on the show throw up what I would consider a temporary shelter, only look at daily subsistence as a goal and really aren't looking ahead to being prepared for a long, wet, cold winter. This is why I think Nicole made a mistake.
Lastly, I think it's one thing to go out in the woods in Ohio or wherever and learn how to build fire, trap, etc. and have some basic survival skills. But, it's a completely other thing to not have any experience actually privative camping. I'm surprised how freaked out people are by bears on this show. They aren't uncommon and by being smart (e.g., not cooking where you camp, hanging smelly items up in a tree) you can mostly coexist with them safely. I'm by no means a primitive camping enthusiast, but I have had black bears come into my camp when I was backpacking or canoeing and scared them off by beating pots and pans together and throwing rocks at them. Nicole is aware of that, but it seems not many are.
