    Default Dry Ice?????

    I am packing for a 10 day float hunt and wondering about using dry ice?

    Have you done it?

    Can you fly with it?

    Can you put it in a regular cooler?

    This is from

    As a general rule, Dry Ice will sublimate at a rate of five to ten pounds every 24 hours in a typical ice chest. This sublimation continues from the time of purchase, therefore, pick up Dry Ice as close to the time needed as possible. Bring an ice chest or some other insulated container to hold the Dry Ice and slow the sublimation rate. Dry Ice sublimates faster than regular ice melts but will extend the life of regular ice.

    Not sure that it would be of any use.

    Default Dry ice issues

    There are a number of issues that make dry ice impractical for float trips, in my opinion. Here's an overview:

    1. Travel on airlines. You are limited to no more than 5lbs per package. This means a cooler, or whatever. Coolers cannot be sealed with duct tape or anything else that keeps the cooler from expanding as the ice converts to a gaseous state. In other words, the cooler has to be able expand if dry ice is inside.

    2. Ice is not necessary in most cases. Freeze your perishable foods in flat layers and load them in the cooler in the reverse order you plan to use them. This allows you to open the cooler only to take a meal out, which helps prevent premature defrosting. If the cooler is full when you start, and everything is packed tight, it will thaw slower.

    3. If it is warm out, consider burying your cooler in the ground up to the lid, then cover the lid with a chunk of sod. This insulates the cooler and it will stay frozen MUCH longer.

    4. Avoid opening the cooler any longer than it takes to remove an item.

    5. Keep the cooler in the shade!

    Hope it helps-
