Kilometer stone? In the USA, certainly NOT! (In any case, if you want to be metric-silly, shouldn't it be kilometer-6.35029 kilos?)
My recent milestone - attending my first-ever AccyWeb gathering during my recent visit to the UK.
Another milestone was going to a cricket match and having the rudiments of the game explained so a baseball fan could understand - and enjoy (or was that due to the plentiful refills of cider).
Congrats, grannyclaret on your deification!
