Mmmmm.... carrot juice.
At the local supermarket they carry a wide assortment of juices and I recently tried carrot juice. At first it seemed a bit odd tasting, but after finishing one bottle of the stuff, I found myself growing attached to the flavor. Now, after drinking it for a few weeks, I find it very cool and refreshing and I'll often find myself craving it when I'm thirsty. I find it's much better than any soft drink, although I don't know if there's any downside to getting all this extra vitamin A. Just one glass has about 700% of the US recommended daily allowance and I'll usually drink a whole bottle in a day.
