Hi Trevor, if I knew where you were I'd have arranged to meet up for a drink (Coke of course). Hope to come down again soon as I miss Devon having lived there for a long time in Plymouth and Exeter. Regarding variable speed limits Peter, if you ever drive down the M4 through the tunnels at Newport they've got one there which isn't obvious. It apparently gives the local council £250,000 a week in fines. Lyn
