Boots and a pack have worked unsurprisingly well for me for over 40 years. But you do need to do the research on area/population.
Damned few people are willing to solo or partner pack a moose for a mile or more. My last one (2014) was a 30 yard snow machine drive up to (the one before was a solo one mile pack), and one in the 70's I drove the boat up to within 50 feet. My biggest was a half mile pack. The other 19 were somewhat longer...
The farthest was a small yearling @ 5 miles or so- 3 loads. Heavy loads.
Thank God I got old!
Caribou packs have been up to 12 miles.
Last 6 years in Kotz, I drive the snow machine or ATV up to them after the kill. I kinda like that for meat getting, but foot stalks have always been the most fun.
Thank God I got old and moved to Kotzebue....
