I guess it's ok if you sink a big old warship and call it a "reef." In fact, it's not only OK, it's an economic opportunity. Project officials expect the $8 million cost of the project to be recovered in just a year of wreck-diving related revenue.
I like to dive underwater and look at things, but I've never understood the fascination with diving on wrecks. I'd rather look at ocean stuff than human stuff underwater. If I want to see deteriorating hulks, I can just go to a junkyard.
The warship Vandenberg was all done warshipping and needed to go somewhere. So the Key West Dive community put together an effort to sink the ship where divers can enjoy it and spend a pile of money enjoying it. Call it economic development. I wish they put the effort into natural habitats, making natural diving better.
Oh well, nobody asked me.
