Just got back from 511. We were lucky enough to bring out a couple bulls, and a buck. We are further up around the Marten Hills area though. The deer sightings were plentiful, even saw the biggest spike i've ever seen. Must have been 16" tall.
Never had a chance at him, but there was a real hog around km23 on the west fawcett lake road.
I have to agree, the traffic is getting terrible up there. Lots of road warriors, and guys that think the sound of an over-revving quad engine works as an animal call
Get deep in the bush, don't be affraid to walk, and your success should present itself on many occasions.
Good luck, have fun.
