I remember 1980 eruption. That ash chokes air filters on cars, grits up you hair, gets in the corner of your eyes, aggravates your existing hayfever, and makes for gray boogers. And unlike a silica based ash or pumice, it does not insulate against electricity. It conducts quite well and sometimes will short out electrical serivce. Just think gray snow. If it's on your car you can't wipe it off 'cause it will scratch paint; gotta bLast it with a hose. It took about 4 years to make it totaly disappear.
