In Washington we also buy cars manufactured to "California Emission Standards." Whatever that is. California has much the same problem Wisconsin has, too many government 'solutions.' I always fill up in the last station in Arizona and Oregon before entering high priced CA.
BTW, on Feb 19, we paid $3.07 in Florence, OR. When we pulled into town the night before, it was $3.05.
