Question about arctic grayling

[pixe1334]

First of all, I want to say that I'm not looking for anyone's secret spots or anything like that, just looking to see how close I have to be to the mountains to have a real chance of finding arctic grayling.

I was looking at Athabasca, mcleod, freeman.

I've been thinking of maybe going to Athabasca river around Whitecourt (I know there's some stream north of Whitecourt but I don't remember the name), the freeman river, or maybe the mcLeod around Edson or something like that.

Would I need to go a lot closer to the mountains to have a decent chance of finding any?

Oh yea, just a general question, I'm assuming there's mountain lions around those areas? I'm probably going to wait until I can find someone to go with me if that's the case.
