Ill fill you in since you're not that sure.

We ran out of gas on the highway.
Me and Luke walked ahead, 15 minute walk, we took a turnoff for the gas station, whilst everyone else waited on the highway.
We met the new guy, Conell.
And so you could just drive up the off road, leading to the High way, meeting the gas station. 
Or drive up the high way, meeting the rest instead of us. 
But if you were low on gas you'd head for the gas station I think.:)
Hope that helps, but you should really read the posts, or atleast the recent IC just to get a general understanding? Your choice, could always just catch on:)
