Go ward driving and find the suckers you can connecto to. then use something very directional and hone in on them.

Then again, build the Mother of all nodes (like me) and wait until they start coming around asking questions.

As an alternative, build the mother of all nodes, grap an amplifier and swamp ann the channels. You will soon figure out who they were whe they come around and pull your mast down.

The latter is not really advisable as it also may cause you more greif than what its worth.
