Thanks for the encouragement Mag.
I decided to get the Lone Antenna out of the way
Went back and checked the radar screen and I got a kind of bird sound when the line hit that last dot.
So I guess it's okay.
Wonder how many virtual miles I've walked in this game
Now I have to figure out which dots go with which panels.
I think I have an idea with the clue you gave about the 9th wedge.
I don't want to post this here in case it spoils it for someone else.
