Nice try at rescuing your game from the smoking ruins!
Goodonya for coming up with a fun plan, but I think I'll go the inland route to Lawrence. Although your road is one I haven't been on. I have seen the highway a couple of times
The road sort of follows the Clarence River, with a couple of ferry crossings, one at Ulmarra, and the other at Lawrence, it's a very pretty, peaceful, slow ride along narrow good quality sealed roads.
The ferry rides were a nice change of pace too.
Ulmarra:
Lawrence:
I'm looking forward to riding it again, one way or the other.
