In 2018 we had big changes in temps in our fly in. Once we deboned my caribou and packed it back to the lake, we laid it all out over night on a tarp, before putting it spaced out in game bags and then putting the game bags in heavy duty contractor bags(to keep dry) sitting in the lake for the day and a half we waited for the plane.. it worked for us, not sure what everyone elses experience is with that.
