Well after 3 1/2 years and (counts on fingers) 6 players dropping out with another 4 dropping there is only one original member left (my fiancee) in the group of 3-5 players I run with now.
They are the cream though - not the greatest group I've ever played with but the second greatest certainly. The only thing I would change is to move 2 of my players back to London so we could all play every week (right now we only see them every other week at best).
