This is great, I think we're getting somewhere. Until I read the last post, I was thinking it would be good to start with Admin, but if Maggots plan could work out, that would be a great way to get going...
I'm not sure about multiple jerseys, but then I do have a very linear way of thinking, so I favour one jersey doing it all, rather than lots out there at once, like a mindmap. Never did 'get' mindmaps...
I'm thinking that the best way to run it, once going, is that the holder(s) of the jersey post on here to say they have it and how far they can take it, and then folk nearby can arrange meet ups etc - although obviously, ideas are already forming. The map will allow us to see who's likely to be nearest, and also if there are going to be any insurmountable gaps. And I feel we shouldn't try to be too efficient, at the expense of anyone getting their go - so if it has to return to an area because someone was away or working or whatever when it came by, so be it.
It would be great if a log could be kept of the jersey's(s) approximate route, so that it can be drawn on a map later...
