I has assumed that we were so cool and together over this way, that while those Eastern Staters were arguing over who was making what and which bottle was being swapped for what, that 10 to 15 blokes would just quietly turn up at my place at the start of December, swap cases, drink a few beers, and head off again.
But if we are going to formalise it ... I'm in, we can use my place for the swap if we want, having switched from bottles to kegs I have an enormous number of long neck bottles for anyone who needs them as well.
