I get mine from Hillsboro inlet every two weeks. And while I'm there, I usually see the commercial trucks that sell it to the stores pumping into their tanks.
When gas prices were lower, I would go offshore to get it but I have found that on a strong incoming tide it's just as good at the inlet. I stay away from doing it on the weekend when there is alot of boat traffic and more pollutants there.
Since I live close to the inlet, it's worth it to me. Since you're in Davie, you would have to weigh the expense and time for you to head east.
