Forget the .300, the .308 makes the trip as long as you have great confidence in the rifle,

Borrowing a pack, similar to borrowing used underwear, Bad idea. Buy your own and start getting familar with it now, Sell it when the hunt is over.

The most important things to me were body care, Good snythetic underwear, 2- 1 oz bottles of Goldsbond medicated powder and baby wipes, followed by good socks (bridgedales). You start to chafe, and things become horrible..

Forget the fishing poles, you're sheep hunting, fish at home, not to mention it seems your not counting oz, and you better be.

I had no Insects in The Alaska range either time I was there.

Go absolutely no where without your range finder.(still in therapy over this).

Who is your outfitter if I may ask?
