It's hard to think of Liberty as an "offshore" oil development.  There is a huge causeway that goes past it on the way to Endicott.  In the summer they even have Endicott Causeway fun runs that go past the pad where Liberty drilling will be staged.  The pad itself has high berms surrounding it to prevent spills from reaching the water.  So it's hard to think of Liberty as "offshore" when you can drive, run or walk to it.
