If you're tired of paying too much at the pump, you could explore public transportation. To help people deal with high gas prices, DART is lowering the prices of their bus fares to $1 through May 31st. It may not be practical everyday, but maybe if you're coming downtown for the weekend, it's a less expensive option.
Be glad we're in Iowa and not other places. I traveled to Chicago over the weekend and paid $4.66 a gallon for gas!
