I don't think I am being over harsh at all, if one group of people can't make it then the whole point of this being an open forum and not a fee paying club is that anyone can turn up and ride if they are available!!
To insure one group of people are included just cos you know them is infact even more likely to exclude other's you don't know, because it becomes a click, quite quickly, I once joined a club were everyone had known each other for year's and such a click had developed, they then were constantly scratching their heads wondering why they had no new members!
I also it's a non starter fishing around for dates when people are available, just doesn't work, you are never going to please everyone and that is the way of it!!
Steve did a great job in setting out, dates that people could pick up on and go with, if were not carefull the whole free easy come easy go feeling will be lost!
