Still not sold on the highway pitch, my character would probably vote against scavenging a narrow "graveyard" with little room for safe retreat. There are plenty of other options, but there are places that are bad ideas 99% of the time in survival horror: highways, hospitals, shopping malls to name a few. I mean it's been two years so a lot of the 'dead' probably have moved on from the highway but even then it does provide a careless risk no matter how much bullets we have. Just my two cents.
