Lisa, are you planning on taking Hwy 1 from Santa Maria to Pismo? If so, consider a route from Foxen Canyon to Dominion to East Clark. There is a Unocal station on the corner of Clark and Bradley, and an Orcutt Burger on the other side of the intersection. From there Clark tees into Hwy 1 just past Orcutt.
(A bit of trivia: a scene from the movie "Sideways" was shot in the Orcutt Burger, and one of my mom's friends was an extra in the background. The town of Orcutt was named for a Union Oil engineer, or geologist(?), and originally consisted of company houses (shacks
) that had been relocated to the present location once the wells were drilled.)
