HELP - Recover Pitch from a Barrel

[Rapidy]

Ok, so I'm doing this quest so I can level up a bit more and I'm stuck. What I'm doing is gathering material for John Smith so he can fix his ship. I already did the other 3 requirements, I'm just stuck at finding a pitch from a navy barrel. First of all, where do I look? Since John Smith was on Driftwood, I decided to check there, but when I found a barrel I also found the "Nothing Interesting Here." sign come up. My quest journal gives me no clue to where I can look. Any help or suggestions would be greatly appreciated.

And Happy Fourth of July.
