If you do get this together and hold it at an interesting location somewhere, then I might be able to come along. I don't mind travelling and in the past 6 years have made almost every meet that the forum has had throughout the country.
In my experience Sundays are usually the best day to hold such a meet as many people now work on Saturdays. And if the weather holds, as long as there are alternative attractions close by then it could be combined with taking the family out for a drive /visit. We have had several successful meets in out of town shopping complexes, park areas, or local attractions as long as there is a big enough area to accommodate a collection of cars.
There have been combined meets with the 323f & MPS guys before so it is possible to round up a few people. So please do go ahead and see if you can make this happen, hopefully before the winter sets in.
