I just filled up my pickup truck (Ford Ranger) for only the second time since the new year. It cost about $60 to fill. When my wife complains about me buying bike gear, I just pull out the gasoline bill. Last time I did that, our monthly bill was something like $260 and it was all from filling her car; I didn't have a single charge.
I'm saving some real change with gas prices so high right now because I'm bike commuting 30 miles/day. I also gave up my parking space at work, which was costing $15/month.
