Gosh I don't even know what it is, I hardly ever buy gas. Since I walk to work Eric mainly puts in the gas in our car. I think the cheap stuff is around $2.80 though, or it was a few days ago. I'm almost glad that my car was junked last year- I'd like to have my own car, but I'm thinking instead of investing in a good bike. It's free to run and I'll get some exercise.
