I'm not sure if you are talking about the place I think you are, but if it is what I'm thinking you need to shoot out the wood block holding a trailer in place. It then rolls down and clears the way for you to continue.
I agree...everyone seems so eager to bitch about these things. Fine, it kinda sucks for people that pre-ordered and won't get the game until after it is in stores and everyone else is playing it (and who wouldn't want to play Max, I'm heading to EB tomorrow!), but don't people have more going on with their lives than to have this be so upsetting?
