Eat yourself sick for 3 days, then bury the rest? Those with an interest may find the topic of Charcuterie fascinating.
Keep it slowly simmering for a couple of weeks, adding water & veggies every day?
Bury it in beach sand, and let it sit over the winter, then drink it?
Or maybe lace it with with poison, and hope the nasty neighbors steal it. ;-)
Salt cure/corn; jerk; brine & smoke; pressure can it.
For long term keep of game meat without means to freeze. Cut up meat with the grain, in strips, slow smoke or dry it for jerky. No, it won’t be the same as the bagged flavored and tender jerky you get at the grocery store. It will be rock hard, require soaking in water to be cut up for cooking. Or, can whack off a chunk with axe, then chaw on it for a few hours to pass the time.
