Did that hunt in 2001 .Hunted with guns and had to be 5 mile from the road but worth it .
Take a raft to get across the sag,

i found one in a tire shop in deadhorse and payed to use it a couple of days.You are going to love it ,get a photo of you in front of the artic circle sign with your local paper in hand .Pee in the yukon shoot a grezz and do an native and you will be a sourdough.Goodluck PS there is a great alaska hunting forum out there.
