My six year old daughter turns seven August 27th. Since we will be camping that weekend at the same CG as the in laws, we figured it would be fun to have her birthday cake at the CG. Thinking about it, I am not sure where a store is with a bakery anywhere near the CG so we will need to take the cake with us. It will take up one whole shelf in the fridge if we do and how do I keep it from getting messed up during transport?
