It is possible to tell how long a car has been driving by noticing how much of its exhaust is visible. Why is this? Thanks in advance. +-------------------------------------+ +------------------------------------+ | USENET: decvax!ittvax!sii!dmcnh!gts | | DISCLAIMER: The content of this | | USMail: 14F Hampshire Dr. | | message is the sole responsibility | | Nashua, NH 03063 | | dmcnh!gts and does not necessarily | | NEBell: (603) 880-2069 | | reflect the policies of Datamedia. | +-------------------------------------+ +------------------------------------+
