Wow, 3 whole stations in the city of Houston.....so, let's look at the demographics here....
656.3 sq mi
Population (2009)[1][2]
- City 2,257,926 (4th U.S.)
- Density 3,897/sq mi (1,504/km2)
- Urban 3,822,509 (10th U.S.)
- Metro 5,867,489

LOL

Yeah, that's an awesome ratio right there per density....very practical. Why didn't we all think to run E85? Oh yeah, the ones who are close to a station probably do, the rest, we make due with other methods.
