Our Proposed Route

I think we'll take I-90 across the United States from Seattle to Chicago. One possibility is that we'll stay in Missoula, Montana; Rapid City, Sout Dakota; and Rochester, Minnesota.

The most likely snag--my car. Since I got my 30,000 mile maintenance--rough the same time I came up here, my mileage has gone done. From about 350 miles per tank to 250 miles per tank. I'll keep an eye on my mileage. I hope it's something like Canadian gasoline additives or something. Hmmm.... Here is a snippet of my mileage. Note the mileage is only accurate for the times where I filled the tank to the top.
