The Indianapolis Star reports that school officials across the state are toying with the idea of moving to a four-day school week in order to cope with rising fuel costs. Prices, which already eclipse $3 a gallon in some parts of the state, could jump even higher in the winter months, officials say. By moving to a four-day week and adding an hour and 20 minutes to the school day officials estimate they could save $1,500 or more in gas prices alone, the paper said.
