We do eat pancakes at other times as well, but Shrove Tuesday is essential. Try a search on Pancake Day or Olney, where they have races tossing pancakes - I don't know if anything is there.On the other hand, I do know there are a number of Bonfire sites, or try fireworks for links to all that is left of a fine old tradition of sending up authority rotten. My feeling is that to allow a tradition of rebellious behaviour while appearing to condemn it and trying to ban it is a very good way of keeping dissent under control.
