Hey dude, good luck with the 'goat hunting up here. as a South Dakota resident I have about 13yrs experience in SD Goat Hunting and it HIGHLY depends on where you go. What county are you heading to. (or town)
Where I go, Bennet Co on the south central part of west river there are basically two kinds of goats.
The Sage goats that stay in the sand hills are easy to hunt. Very curious, and are not easily spooked if you shoot prone and have not made them aware of your presence. It is fairly easy to spot and stalk as long as you approach hill tops VERY slowly. (i would recomend a ghille suit but a prarieghost type camo will work)
Now the goats that venture up to the pastures/alfalfa are another story entirely. Out in West River SD, those lil bastards will climb up on top of hay stacks, and piss all over them...and THEN the cows want nothing to do with that hay supply. Farmers and Ranchers will chase and flock shoot at them just to save the hay. Very much more skid-dish around vehicles, will NEVER give you a 2nd shot and will probalby know you are there before you ever see them.
As for hunting in Jan, no worries...just prepare for the worst nasty blizzard you can imagine and then just hope we aren't having one, and I am not really kidding.
