why can't we have one?
Great Idea !! You could start a campaign for one.
Pick a day, say 2nd week in November. You should go for a big one in central London,
and if you're really ambitious you might try for smaller ones in every city, town and village in the UK.
If you write to the palace they might send a royal to possibly lay a wreath at the tomb of the unknown soldier.
You never know, it might catch on, people might even remember it
