But this one surely would be in my Top 3.

....I live in Wash state and I was caught in the Mt St Helens ashfall....my hubby 10 yr old dtr and i were on the free way heading some 45 miles away to his sisters house..to which we had never been before. The boom the smell of sulpher the lightning..but no rain clouds..wtf is going on? All we could think of was the mtn blew and nothing on the radio for the first few minutes. We finally made it to our destination and we filled up the bath tubs with water..lit a joint and put THIS SONG on the ol stereo opened the windows set the speakers out them and played this full blast. They were somewhat rural so we werent blasting any neighbors. It was mid morning and pitch black. The birds quit singing..it was dead still...except for Floyd!
