I wish BioWillie would come to Houston. Right now, it looks like they're just focusing mostly on the I-35 corridor between Austin and DFW. Houston has I-10 running through it, one of the important east/west transcontinental interstates that sees a LOT of diesel traffic. I've sent an e-mail to them asking when we'd see it in Houston (a futile attempt, I know), but got no response.
C'mon, Willie, I know you have a E320CDI so you just "might" be lurking around here, and perhaps if you're reading this I suggest you open up your next location in Houston.
