I'm at Sand Traps. I reach this wall that's wooden and all messed up. I just shot up a bunch of Combine Soldiers. I have my Buggy, but can't get passed. What do I do? I've been trying and trying over the past hour. No luck.
There is a spinning fan nearby-up high. And an ocean to my right. Abandoned and destroyed cars are littered all around.

A little help here please.
