Ice Man Speaks!
I was co-owner of Harold's Ice Inc in San Fran in th late '70s and a avid camper. Easilly got 10 days with a 12"X12"X12" block of dry ice (-72*) in an aluminum Coleman ice chest. Packed in frozen food, and frozen steaks. Fill any unused space in the chest with crumpled newspapers...air circulation is the enemy! Cover the ice chest with a heavy, insulating shipping blanket and only uncover and open once a day! When you remove something, insert more crumpled newspaper. Good for 10 days in the summer in northern Nevada, and it was hot! Steaks still frozen solid on day 10.
Second Ice chest for drinks and vegies...used 25# block wet ice, got about 4 - 5 days, but what the heck! Again, used newspaper to cut air circulation. Cooled the beer in a stream after that and all was well! Vegies arn't all thier cracked up to be anyway...
