Information to keep handy?
I was just making myself up a little card to keep in my pocket with a few bits and pieces on, I thought I might put a ruler along the edge and some other reminders.
I was thinking maybe RT reminders, transponder codes, useful telephone numbers that kind of thing, just something I could always have at hand.
I just thought I'd ask around first and see if there was anything obvious that I'd not thought about, any ideas?
