Roachie, yes there is a show in Port Broughton this weekend, its being held by the SA N Gauge Society as I think one of there lads is a resident there
Sat 5th & Sun 6th October in the Port Broughton Community Hall, 9 am to 5 pm
Afraid I cant say which layouts will be there, probably at least the N scale 'Strathalbyn' and 'Portland/Greater Portland'.
In regards to the swapmeet, Ron has it right. Also there are Drinks and a sausage sizzle available as per usual. anyone looking to get a sellers table in can still get in touch.
