POWERFUL EARTH CURRENT ENTERS NORTH AMERICA FROM THE PACIFIC
An immense current of terrestrial electricity originating somewhere in the Pacific enters the North American continent along the Strait of Georgia (between Vancouver Island and the British Columbia mainland) and shoots past Tacoma toward Oregon. The discoverers of the current, John R. Booker and Gerard Hensel, at the University of Washington, traced the flow of electricity through a narrow wedge of porous, water-bearing rock that parallels a fault line. Another branch of this terrestrial circuit enters along the Strait of Juan de Fuca. No estimates are given of the magnitude of the current; and there are no speculations as to the origin of the electromagnetic force driving the current.

In some areas, large artificial earth currents are created by high-power transmission lines (WRC)

Got any high-power lines in the area ?

Anyway, you may have gotten juiced a little by this ground current maybe. However, I would think there would have been many reports of this throughout the area if it was the source.

Have you chatted with your neighbors to compare notes any? Maybe it was a wider area effect than that.

Just when you thought it was safe to go back in...er...out...:-)
