Re: beware of rubber static shock
I remember that, many years ago, gasoline trucks would have a metal chain hanging under them that would drag on the road to drain any static charges away to reduce the possibillity of a spark. (My guess is that they probably stopped doing that because the mechanical action of dragging a metal chain on the pavement probably caused sparks or that the truck now became a lightning rod.)
Maybe you might want to think about dragging a metal chain???
