Met a few locals in Deni. They said chips always come with black sauce in Deni.
The locals said the chips with black sauce were from the Black Cat or the Lucky Chicken. The former wasn't open yet and the latter didn't know what the hell black sauce was.
The road from Deniliquin to Barham was devoid of life. Nothing but road dissappearing into a shimmering reflection. I tried to get a photo of what looks like water over the road, but it's just a mirage.
