We pack our bags and fly about 4,000 miles from Chicago, Illinois, to London, England. As we drive towards Cleethorpes, we visit a farm to try a scoop of cold, creamy soft-serve ice cream. Next, we look for the line of zero longitude in Cleethorpes. Lastly, we buy a local brewed lager at the Signal Box Inn, a pub in an 8 ft by 8 ft building (2.4 m by 2.4 m).
