My tactics for saving on gasoline include topping off the tank when it's at the 3/4 level. Why wait until it's almost empty and pay ten cents more a gallon? The price isn't coming down even after the weekend. I'm combining errands, making fewer short runs, and have all but given up rides in the country. Ouch, that last one hurts because it's something I love to do.
Please note I've added several links to my blogroll. Randy Ingermanson's Advanced Fiction Writing Blog is a daily stop for me. Check out the archives. If you sign up for his newsletter, he's got a bunch of freebies for you. By the way, don't be put off by the word, "Advanced." There's something for everyone here.
