Hi Rollin, that is interesting....did you find that it worked well for you and lasted a long time? here is something I found on another forum <br />"<div id="post_message_95619">Cube ice will not last, so just forget about it unless you absolutely want it. Anything next to dry ice will be frozen solid, so tough to cook a frozen block of meat. Here is what I used to do when I camped out in CB for a summer with just a run of the mill type of cooler. I would use a combination of dry ice and block ice to keep my food for a week at a time before I would hit Gunnison up for supplies. I would have the dry ice next to a block on the sides, with the food I was planning to use quickly in the middle. I would put stuff I was not planning to use immediately with the dry ice. The dry ice would keep the block ice from melting for a few days and also keep the stuff next to it frozen. By the time I ate through the supplies in the middle, the dry ice would be gone and I would start on the stuff that had previously been frozen. It takes some experimenting to get the right setup, so you will have to improvise on the go." <br /><br /><br />I know I have seen it in other places and when I go the local stores next I will look (providing I remember...LOL)<br /><br />I may be totally wrong about it being not good for refrigeration....these guys do it.<br />You are right about cost...it is about $2 a pound...<br />Bri<br /><br /></div>__________________
