I do keep track of the sites in remote areas that for some strange reason have good reception. Often I may drive 20 kms to get to the spot we call "Telephone Rock" only to find other people there doing the same thing.

That is one of the reasons I am coming to visit your neck of the woods. If you happen to notice the bad spots, make a note (GPS?), and maybe I can help.
Don't go out of the way to do it though, I might be unable to change anything..
