Melvyn,
as one who has started many's a topic on this DG only to see it disappear to the 2nd and 3rd page with undue haste, I implore you to NEVER delete something you have begun.
The largely American audience of this DG do generally prove to have little interest in very UK-based threads, and quite rightly so, for much of it is outwith their knowledge. Similarly of course I tend to avoid threads which ask for opinions on US and International subjects which are unknown to me. As an eg, I have never contributed to a thread on Merion or the Australian sandbelt. I can add nothing to those debates and, until such time as I can , I stay well clear.
Your thread had something like 650-odd reads before you deleted it. Trust me - that is close to being VERY interesting to GCAers. The fact that few chose to reply merely indicates their lack of knowledge rather than any lack of interest.
Your Posts are always interesting, sometimes thought-provoking and occasionally splendidly inflammatory. PLEASE don't stop, don't delete and don't despair. Threads are only interesting to people who are interested in them.
Remember, only 5% of Americans actually have Passports and only 5% of them actually ever use 'em. (I made up these figures, but they're probably not too far from the truth...
)
FBD.
