Gas prices have been shooting up this year because we are in war with the country most of our gas comes from. Gas prices today in New York are up too $3.00 or more per gallon. That doesn't sound like a lot right? Wrong. A Toyota Sienna minivan holds 20.9 gallons. So one full fill up would cost at least $62.70. Gas is taking up a lot of money and by the way it's going it looks like the prices will keep rising. The gas prices keep going up, and up who knows when they will ever stop.
