Back in the 1990's, before the internet, I was sending money every paycheck to H&A Industries for fuel economy info. The renowned "200 MPG" book trilogy from Allan Wallace was probably one of the most influential products offered -- not only influencing me, but thousands of other folks. I met Allan in 1999. He is from Texas, but was in Salt Lake because his daughter was undergoing cancer treatment there. The picture is of me, Allan, and my best friend at the time Grant Goldade.
Part of the MPG Basics video series, I did a segment on Allan Wallace.
