I see "Ibusuki" but not sure how we get to allow "Nagashima" since it is an English forum after all.
I went out this arvo, hunting. Too many suburbs and even local small towns have no signs. Frustrating. Plenty of business signs, but that's not the game.
I found an "N" for chains but it was on a round-about and I wasn't stopping there after having a Copper pull up beside me at an earlier sign and point out a "No Standing" (i.e. an "S" with a slash) sign 5 metres behind me. He let me go but it sure adds to the challenge! Funnily, in the time it took him to explain my sin, (I had to take my helmet off to hear him across the car) he had accumulated two vehicles behind him on what is a fairly quiet street.
Good luck with the "Vs" Shillas. There are only three widely spread across Brisbane, and one of those is only a locality, not a suburb or town.
