Hunted POW the 3rd week of August last year. Stayed in Craig and used the road system. Saw few deer - 3 total, in fact - all does. Hiked high to multiple locations and couldn't find deer. Other hunters we ran into had the same luck.
One piece of gear that I'd recommend is a pair of micro spikes for your boots. I've used Katoolahs alpine climbing before, but never the micro spikes and they would have helped greatly.
Can't tell you how many times me and my hunting partner had our heels slip out from underneath us on the grass/vegetation heading downhill ... but plenty. My hunting partner actually fell so hard on his rifle he broke the stock.
It was wet and soggy. I alternated between wearing my gore boots and gaiters and knee-high muck boots - even for hiking. Pretty much impossible to stay dry in the boots/gaiter combo.
We found plenty of pinks, but no silvers, in the rivers and bays. We'd head out and hike/headlamp up for deer in the early AM, back in the afternoon to fish until dinner, then ate salmon every night. Didn't see any silvers and you could use a 5 weight for pinks.
Rented a truck from Hollis Adventure Rentals and stayed in cabins recommended by them in Craig. Overall awesome, flexible set up - if only there had been deer. We took a float plane from Ketch to Hollis, then caught the ferry back to Ketch on our return trip.
