Here in Illinois, I generally need to ride 50-60 miles just to get to the better riding. While the ST is great to get me there and back routinely, It does start to give me pause when a single fill up approaches $30. I really think she runs better with 91+ octane, but I have gone with some of the cheaper octane recently to offset the high cost. A ~300 mile day trip is now costing about $40 in gas alone. Illinois/Cook Co has some of the highest prices in the Midwest. I really feel sorry for our European counterparts who probably view our prices as cheap.
