500km... I don't think so. Wilson is a small pocket in Kanyaka.
Must be another "Wilson" then, this is the one I found.
Anyway Kanyaka it is.
The pic is of the Mighty CB13 with Mrs W behind the bike, and the Kanyaka Homestead ruins in the far background. The Homestead must've been really something in it's "day". Above the Goyder Line, it flourished for a few years, but the drought (normal rainfall) came and the Homestead, like many other towns and settlements above the line, perished.
Sad story about the owner who drowned when the river bed behind the Homestead became a river.
Enough of that, your turn.
