The places I've been visiting are only about 25 miles south off I-15. It won't take much of your gas. I have a 2.5L dog and the round trip only takes up a little more than a quarter tank of gas. How about Tuesday, October 4 or the next day? You'll have a whole week to save up some gas money.
That may be the only time I have to go for a while. Depending on how surgery goes on the 6th.
