Maybe more off topic but a safety reminder for those with oxy/acetylene tanks. Yesterday at Seattle on Interstate 5 this truck carrying oxygen/acetylene tanks suffered some sort of catastrophic failure. I'm sure we've all seen these trucks carrying bottles. If you've ever wondered what would happen if your tanks exploded here's your answer. Note the one pinwheeling down the lane at the end. The driver escaped and no one was injured. Sorry about the ad at the beginning.
