For transporting food the Polarbear is probably the most convenient and cost effective choice.
I bought a Polar Bear cooler for my CRC house sitting trip in August. It did keep 30 pounds of tightly packed steak and shrimp frozen solid for 3 days but not such a good job with ice and drinks. Filled with about 15 pounds of ice and 12 previously chilled beers it only lasted about 30 hours in shade. Almost any hard cooler would do better than that.
Travel is fatal to prejudice, bigotry, and narrow-mindedness, and many of our people need it sorely on these accounts. - Mark Twain
