Sherpa, you're going to need more info than I can give you, but here's what I have.
I met BillW via internet and he mentioned that he and his hunting partner would like another guy or two to join them. They sounded like great guys, the hunting sounded excellent (they'd checked references), and I joined them. It was that simple.
I considered the Mulchatna herd which has produced huge trophies, but its numbers are way, way down. The herds in NW Alaska are some of the strongest. Some estimates put the numbers at over 500,000 caribou.
I briefly considered the archery-only zone bordering the Haul Road, but heard a few positive things, but many negative comments about road hunting, too much pressure, conflict with other hunters, etc. I know that other Trad Gang folks have gone and enjoyed it, though.
I think the hunt was physically easy compared to hunts in the high Rockies. I walked about 8 miles one days, light daypack, temps in 50s and 60s, less than 800 feet elevation change. When we packed BillW's bull, it was about a 1/2 mile uphill in driving wind and rain, but again, pretty easy compared to what one could face in Colorado.
I think our hunt was one of the first of the year for the outfitter, although the season is open year round (please doublecheck the regs). Temps were especially warm on some days - over 65 degrees. We were supposed to be there 1-8 Sept. Any earlier and the antlers wouldn't be fully grown. Another two weeks later and the bulls would be rutting. For a lot of folks the meat of rutting bulls is very unpalatable.
Travel time should have been a day each way. That's what it took on the way out, but our outfitter got us out a day late, then forgot to pick us up as scheduled. That cost me an extra three days because of problems with flight schedules. Weather can be the biggest driving factor and you could be camp-bound for an extra week if things go south.
I've had caribou several times and feel it has its own flavor. Not bad at all, but honestly, I prefer it as sausage.
Hope this helps a bit.
