The Yo-Yo goes down

Last week gasoline prices shot up to $2.99, our new record high. This week the yo-yo is going down to $2.78 today. Good thing to. I filled up my tank when I heard it was going up the next day and now I'm at a half a tank full. Though I'm unsure how long to wait to refill to see if it goes down tomorrow. Post later. Bye!
