Going in six weeks. Here are some pertinent items I've established for our trip:
1. Bringing our own tents/ gear. Even if you have to put a few dollars into shoring your equipment up, it's still better to have stuff you can A) tailor to your personal tastes and B) become familiar with prior to entering the field. Also, rental gear, in my experience, is frequently stretched to its limits to produce as great a financial payoff as possible before replacement- i.e., it often sucks.
2. I'm using Arrowhead Outfitters, which fly out from the northern Dalton Highway. Hunted Alaska a few times before, but this will be my first fly-in caribou hunt. I'll be posting a full report on my experience afterwards.
3. We'll be there for the last half of August- this timeline is designed to give greatest access to peak migration numbers on the North Slope, decent weather, best pre-rut meat quality and lower volume of insects. All of these factors change with timing; to your question, if you're there from mid August onward, the climatological data says you probably won't have to worry about your meat getting too warm. Worst comes to worst, bone it out, double bag it with black contractor bags and sink it in a chilly waterway.
4. If financially able, flying in or pack rafting to then hunt area seems to be the gig. Apparently, your chances of success are directly proportional to your willingness to work and skill if you do either of those, whereas even a very motivated and proficient hunter is much more likely to encounter circumstances out of his control when hunting from the road.
Again, I'll post a full report on our experiences on here when we're back... I'll be excited to see exactly where I was right and where I was wrong.
