I'm on the road again, back at Joliet. Regular 87 octane in Arkansas was $3.71 per gallon, across the missouri line $3.57 per gallon, getting close to St. Louis, MO prices climbed to $3.87 per gallon. In Illinois an imediate jump to $3.99 per gallon which was pretty constant until reaching Joliet where it jumped to $4.25 per gallon
