However, with the increase in gas prices, teenagers chose to stay at home instead of going out of the town. “I wish the prices would        .The expense of driving to places is affecting our daily life.”said Alicia, still a senior at Enochs High School in Modesto, California.

Alicia, who spent her summer at her dad’s house, said that there would be no point in getting a job. “The drive to my workplace is so long that I would hardly be making any profit because all my money would be going toward gas,”she said.

Teenagers are now forced to give up the pleasure of driving around the town without purpose.“Instead of driving around looking for something to do, I now find myself planning the way in advance so I don’t waste necessary gas,” said Stephen Macko, a student at Davis High School in Modesto.

What kinds of things are teenagers doing in order to conserve gas? Alicia saves gas by doing all of her things at one time so she doesn’t have to go home and leave again.

“I try to do it all in one trip so I don’t have to always be running around and wasting gas,”she said.“I know that when I go to lunch with my friends, we make sure to go somewhere near all of our houses so we save gas.”“But it’s hard, considering I drive a big truck. I also try to get a lift from my friends when they are going to places that I am going to.”said Stephen. Some try not to accelerate too much. Teenagers will have to continue changing their lifestyles unless the price of gas decreases. However, that might not be a bad thing.
