I choose bou. Moose is a thrill but the work involved to pack a moose very far makes the experience less and less each tim. Bou can be packed out in 2-3 loads and the abundance in NW AK makes it lots of fun. Unit 13 is getting better as well. The real cool thing with caribou is no 2 racks are the same and when you compare racks from the Mulchatna days, to WACH to Nelchina they are all so different. Very cool
