Depending on the weather and how far of a drive home you’ve got, you might not need a cooler. Please read the below before calling me crazy and suggesting this guy needs a Yeti 210 lol.
A few years ago my buddy got an Idaho Bull in 45 degree weather with about a 4hr trip home. We had the elk meat hanging for a full 2 days in the shade and with a breeze while we continued to look for deer.
He didn’t have a big enough cooler - for the trip home he ended up just using a couple BIG plastic totes like you could buy at Walmart that he used to haul in firewood. Dumped the rest of his ice in there and got it home just fine. Elk meat tasted great.
If it’s September that probably isn’t gonna work. This was the middle of October.
There’s ways to go about it without going out and dropping a shitload of money on coolers.
