Do you know if there's a coverage map that goes beyond repeater locations? I'd be tempted to put a repeater on some property just outside Toowoomba, but have my doubts if it'd actually find any other nodes given its location in a valley. Alternatively, next time I'm there, what's the easiest way to find out if existing nodes cover it? [Disclaimer: I know very little about mesh(core|tastic) but think I get the basic idea.]
