Do you have some extra space in your garage or attic? Or perhaps you own an oil tanker you aren't currently using. Or maybe you have a storage unit that's got a little extra room next to an old mattress and box springs.

If so, you may want to call up oil producers in North Dakota and ask if they'd care to send you some free oil, because the crude glut is now so acute that the Koch brothers are actually charging $0.50/bbl to take low grade oil at their Flint Hills Resources refining arm.
