iboomalot,

Re Prius mpg. It is certainly a ymmv. I rarely go below 60 mpg, ever since the weather warmed up to the 50's last month. My wife causes mpg damage wherever she goes :-(
The current tank was at 62 mpg 200 miles into it; two days and 50 lead miles later, it was at 58.5!
Arghhhhhhhhhhhhhhhh
