Like an irritable old codger fed up with the neighbor kids trampling his flower bed, the Earth has posted "No Trespassing" signs all over Iceland. "Nothing says Stay Away better than a hissing pool of mud," reasons the Earth. "And what's more, I'll make it stink of sulfur!" Makes sense, but what do we humans do? We turn it into a tourist attraction! Man, are we annoying.
