im gonna keep on rambling if youve never experienced extreme cold before please take things seriously! be prepared if you break down. im sure your gonna bring plenty of cloths and a sleeping bag. i also bought one of those approved for indoors coleman black cat heaters just in case. there is only one road up there and as deserted as it looks there will be someone coming through but it might be hours or if a good snow storm comes through maybe a day or two. going off the road is a real and deadly concern up there do to the hills and ditches on the sides of the road.make sure the driver is well rested and take turns driving often . keep an eye on the guy whos driving and keep him coffeed up.in case you dont know already 4 wheel drive is no sure thing for gripping snowy and icey roads. i rarely drove in 4 wheel.slow down. i even let a couple pounds of air out of my tires in icey conditionsto get a wider tire print.added weight is actually a plus in this kind of driving. i had a hitch hauler on the back loaded with cans of gas to help with the weight. bring gloves when dumping and handling gas. when you get it on you or your hands and you get inside the warm truck it stinks real bad so take your time filling. get a good funnel and make sure it works well with your particular vehicle so your not taking forever putting gas in . it snowed every day when i was up there but it never really amounted to anything. the cold air can knock you out as you get moving around.dont be a he-man. if your coming from warmer climates like most all of the hunters it would take weeks to get used to this type of cold and your only gonna be there a couple days. i would try to get in some kind of shape before you go.i found myself getting brain stupid when being out in the cold for long periods. your finger become useless and it takes longer to think and do things like working ratchet straps. i would bring that portable heater with you. its nice to warm up your hands while working on your caribou. some guys will sit in a truck with the heat on waiting at a caribou crossing. in some ways i can understand when its minus 20 . i was able to get out a hundred yards from the truck and set up a blind and ambush spot using trees and rocks. a harris or similar bi-pod helps to steady the shots in the cold.things happened quickly for me but if i had to get back to the truck i could.dont rush or over do things. get someone with a snowmobile to haul your game out when possible. i found other hunters helpful to me and dont be afraid to ask for help.
