Hi
Just to prove that we are indeed wise :-)

A Faraday cage stops electromagnetic fields which have time varying electric and magnetic components. The electric component of a radiating field induces currents in the conducting mesh or surface of the cage which cancels the effect of the radiating field within the enclose. So it does not work for slowly varying fields or static fields such as magnetic fields.
But your right in that the County is a big lump of steel and will adversely affect a compass. As others have suggested go for a GPS.
