IMVHO, do nothing but camp and do normal things.
These are inquisitive animals but seem to be generally pretty shy and reclusive.
My belief is that repetition and patterns in the human behaviour in the circumstances you've said would be key.
Repetition and predictable human behaviour may just lead to an animal feeling that it is in control, and if it feels that it is in control, I think that you may just have a chance of an encounter or sighting.
Forget the cameras, for whatever reason they don't work, I have no idea why but they clearly don't.
And don't try to be too clever ether or tricky, because in their environment you're not and it may just be perceived if they are watching you as untrustworthy or another negative type of word that I can't think of.
Predictability can lead to trust though and it's regular patterns that lead to predictability.
Unfortunately the SSR doesn't have enough NW Oregon Cascades data as of right now ( we do have some however if you'd like me to share, so just shout if you do ) but if you are interested in the data from the Cascades on the other side of the Columbia, then I'm your man.
Just shout Joe, good luck.
