110 years ago, all of the houses in this neighborhood were absolutely,
positively shock-proof because they used kerosene lamps for lighting
and wood-burning stoves for heating: water, food, and the living
space.

The 6 States that still use electric chairs are going to be SOL.

I'd vote for 27.255MHz.

Indeed, the second harmonic would wipe out the local CBS's "reality"
program.
