true! Someone in my neighborhood has a leaky cable splitter/amplifier, and I can listen in on HBO as long as I'm wearing the tinfoil and facing in that general direction.
i would go out and do some direction-finding to find out who it is... but, then, that'd be silly, walking around with a tinfoil hat...
I wonder if I can catch more open wifi spots if I wear a tinfoil hat and keep holding my N800 over my head to catch the radio signals.
