This is a WHY would should be Drilling Inland, There is no reason we can't drill onshore, but thats not going to happen with all the Psycho Tree Huggers running around. There is no reason we should be drilling off our coast with all the oil and coal reserves we have onshore.
I also agree we should be drilling more inland as well, however here is a different thought. If this off shore well can produce 50Kbbl/day, we would need to drill only 200 more and we wouldn't have to import anymore oil. It will require upgrading equipment and processes to insure another leak doesn't happen though.
