This is the 21st century, my drinks should come with me, not me go to them. Check out this cool new Roll Bar - Mobile Refrigerator. Once unplugged from an AC/DC power source, it will keep up to 57 cans cold for 5 hours! This would be great on the golf course, just have the caddy pull it, roll it out to where the people are at your next party. Lots of great possibilities. I wouldn't take it with you to the mall though, but what's nice is that you could.
