I started a discussion a while ago called National Snuff Fortnight and Four Years in a Barrel.
It was celebrated from 1st June - 14th June 1987. Only two days left if you want to celebrate in your own ways, or spread the word about the joys of snuff.
I am all for @Vostok idea to mark The Battle of Vigo date 23rd October 1702, if you read up about it you will see it has a big connection with snuff for all snuff takers.
Any interest in promoting 23rd of October as National Snuff Day ?
