Like Lady Penelope, my father always navigated by pub names. He was a fireman in Essex and the best landmarks, especially at night were the pubs. Where the roads had no names you could say "left at The Royal Oak", then past the Green Man" etc. When Harlow New Town was built all the new pubs were named after butterflies and the signs depicted the butterfly on one side, i.e. The Scarlet Admiral and a suitable picture on the other. The fact that most of the pubs were dreadful to drink in was beside the point.
