Another vote for loose and easy. Easiest is, if you are going out for a run somewhere, just post it on the forum and see who turns up. I'm planning a run over to Chipping Norton one evening next summer to have a bag of fish and chips and a stroll around before returning home. Was planning on posting it on the forum a week or so beforehand to see if anyone else was interested. That sort of thing.
Another very good idea!
