Memories inevitably fade for most of us. That's why I always write it all down, in as much detail as possible, as soon as I can. It's not just for the board. It's for ME.
For instance, I went back and re-read one of the old Pebble Beach threads the other day and there were all these little things I'd forgotten... the same is true for the review of the first Eagles concert I ever attended (see review here, if you're interested). thank God I typed all those out when they happened!
