At current prices ($3.79 for premium), it cost me about $.10 a mile. It costs me $.33 a mile to drive my truck (on regular). If gas hits $4.00 a gallon for regular by winter (as they're predicting), I might have to see if I can get a sidecar for the bike! Actually, If I didn't have to drive the interstate to get to work, that would be a viable option.
While I'm not for government intervention, I might support a mandatory 4 day work week. 4-10 hour days, cutting peoples driving by twenty percent, might not lower prices, but it would save everyone 20% of their own personal gas bill.
Fuel for thought.
Anyway, I went on a long ride in the country this morning, and that restored some of the joy of riding. I actually had a chance to get into fifth gear and 'blow out of some carbon'. That's code for "drive fast". I won't say how fast, as my wife is sitting her next to me and I don't want to leave a paper trail.

That said, I'm still doing a lot more riding (bicycle, not motorcycle) these days for this reason. It's a good thing, I think....
Just keep an eye out for all the dead raccoons and you'll be fine.
