I can't help feeling that we're going about this the wrong way round. I'm delighted to see so many people saying that they would consider helping out if needed (and indeed happy to add my name - Oxon, Bucks, Berks, N Hants), but trawling through a great long list of such people with a view to contacting those in the relevant area one by one would be very time-consuming.
Surely something of the style of the "Company on a Perm" thread would be much better? That way, if (say) John Hamilton wanted help at a major control on his Mille Cwmr big hilly Welsh ride, he could have posted here to that effect. That way he might have got local people (like Basil) volunteering, but also maybe some from further afield (like Iddu, me, von Broad and others) who would have been prepared to travel to help.
