I think I mixed these up when we were talking earlier. I see that the former is Sunday and the latter is in 6 weeks.
So what are these bars? I guess I'll find out!
Careful--they might contain chocolate!
Rossmoor bar is simply a "peninsula" formed by a deep S-curve in the river. It's about 750m wide and 750m long. The other part of the S also forms a bar which is also on the O' map, but I don't know if that bar has a name.
So it is on a/the river. I guess that explains the 20cm rocks.
