We don't really have domestic supplies of oil - 90 percent we import. We import a LOT of things that have an impact on domestic production, so though we're a little more shielded than most, we'll feel it too. I can't pretend I know tons about it though - more surface level like you i guess!
BTW we did fill up on the way home and will be filling up the other cars tomorrow. You know, just in case :P
