I never leave home without it.

Not sure if your state lacks them, but Florida has State ID cards for those who can't get or don't want a driver's license. This is primarily used by those who've lost their licences to excessive DUI/DWI convictions (common here in a state with drive-through beer & liquor stores).

You've just described South Florida, and the reason why our car insurance is among the most costly in the nation (we're back and forth at the top over the years with New York and California).

Remember the "don't go to work" protest against the politicians who wanted to round up and deport all illegal aliens back in 2006? (if not, google "Un Dia Sin Inmigrantes") The day collectively called in sick? The freeways during rush hour down here were as empty as 4am on a Sunday!

If it's not obvious, I agree with the person to which I'm replying - Drivers Licenses should be just that, but are instead being used in ways that are detrimental to the original purpose.
Florida has increased the difficulty in getting a driver's license, but not in a way that matters to its purpose. Check out the blue box at the bottom of this page: http://www.flhsmv.gov/html/dlnew.html
Why do I say that it's not a change that matters to its purpose? Because the "driving test" they only put those under 18 though consists of driving through a parking lot! Seriously! (if you're over 18, you don't get tested)
For an eye-opener, google "rudest drivers in America".
I took the test in FL during a summer vacation before I had my MI driver's license... in Michigan, I had to drive though some very confusing and highly congested rush-hour traffic in the middle of Pontiac for my driver's test. Quite a contrast.

A (poorly) trained monkey could get a driver's license in FL, but only if he had enough proof of identity!

I can't remember if it was Popular Science, Popular Mechanics or Mechanix Illustrated, but at least 25 years ago I read an article about an invention that would be ideal for such a spill.
It was a large dome that floated mostly underwater, with a cupula sticking out of the top with baffles that directed waves into the center.
The wave action essentially pumped the oil floating on the surface (and water) into the dome, and since the oil floats, the water was pushed out of the bottom. It was designed to be deployed as an array for very large spills such as this one.
