Dawn, I've just found your conversation online from Canada, and as an ex-pat from Hanley (1968) I found them absorbing. I remember as a schoolboy, going to Chatterley Whitfield to see how a mine worked. Would it be possible, at your convenience, for you to send me copies of your presentations, going back to the beginning? My address is "tpowell1@shaw.ca" I would be very grateful if yu could do this. I don't want to lose old memories; I try to gain new ones. Thanks for anything you can do! Tony Powell
