Last fall I killed my elk the second week of November; which might as well been during archery season given how hot it was. I killed it on a Tuesday, didn't get back to MN until Sunday, and we cut it up on Wednesday night. The temp the night I killed it got down around 30, so I left the quarters out, and the next morning split it between two coolers (an Orion 85 and a Coleman extreme 70).
The rest of the week I was screwing around draining water, adding ice, etc. I dry iced both coolers on Thursday, after this the meat in the Orion stayed frozen solid/frosty until the next Wednesday, but I continued to have to screw around with the Coleman to keep things dry and cold.
Since then I have been thinking about a better way to ensure my kill stays cold during extended hunts in a cooler. A good cooler and dry ice seems to work pretty well, but I feel like I will always have the inkling to keep opening it up and checking on it; which is kind of counter productive. Maybe I just need to build some confidence now that I am using better coolers (another Orion might be on the way this summer), but I have also been thinking about a way to monitor the temp in the coolers either wirelessly or Bluetooth (see below), so they could just stay shut. Anyone thought about his or tried it?
