I hunt in ks where temps can be from 80 to -10. I only gut my deer in the field if i know it will take a while to drag it out or if the path out is long and diffucult. I do however hang and gut my deer imediatly at home, we do this so we can throw the guts in an observable place to thin out the yotes a little. If it is below freezing i will hang them out for 2-3 days meat seems to cool and taste better.
