i was stuck in yakima for four days the last time it blew...and still a very very treacherous drive after that... but... had to get over the mountains...difficult to find panty hose cuz everyone was using them to cover their air filters...zero visibility cuz the ash was so fine that it aerosolized and choked your lungs and your car...not too fun...but i did make some $$ doing ash removal...lol..C
