It was soooo hot today that we had to go on a driving adventure-at least the car has air conditioning. Mom decided to take us to Bad Durkenheim to see the world's largest wine barrel-it can hold 1.7 million liters of wine or 450 people inside.  It's a restaurant and that's where we had lunch at.  Afterwards we drove around some more and saw some neat castle ruins that we will have to check out when it cools down.
