Gassed the car up!

Went to go fill the gas tank of my car the other day (6/15) and had to pay $4.259 per gallon for regular grade gasoline.  I put in a little over 10 gallons and that ended up being $44 total.  It used to cost $30 for a full tank not too long ago!  Kind of makes me glad to have a 4 cylinder, compact car that averages around 29 mpg overall.  Oh, this was at a Chevron on the island of Oahu for anyone wondering where I gassed up at.  I wonder if I should do this every time to keep a record of gas price trends for myself or if it'd just be wasting hard disk space...lol.
