I'd stay off the highways. It's not bad enough that everyone and their mother is trying to get the fuck out of dodge, most of them have succumb to the affliction in the process. Zombie infested parking lots. No chance of getting through them at all.
It's hard to say what else is near the barricade that hasn't already been looted. I haven't gotten much info from anyone who's come inside lately. I think most of them are still too shaken up from what's been going on to even think straight. The last guy we brought in had just killed his own kid. He just stared right past me as he told me how he beat his son's head in with a PVC pipe. He even described the hollow "thunk" that it made as it crushed his son's skull.
Comms are no good, either. No one's been able to get a cell phone signal for days, so I wouldn't count on backup any time soon. I'm still trying to reach someone on the CB from the semi, but so far no joy. Someone's got to be out there, god dammit.
We may just have to reinforce the front of that semi and try plowing through some of the side streets if we're gonna get anywhere, but even that's taking a big ass chance that I don't think we're ready for. We're already low enough on supplies ourselves, and opening the barricade with what little we have would just be disaster.
Hate to say it, but a few of us may have to head out on foot to see if there's even anything left beyond the barricade. That guy who killed his son was the last person I've seen try to come in alive. And that was four days ago.
