I don't have any business degrees, (or any other kind), but here is what I would do:
Cash out of the building and the business for the max possible. Hold an auction if necessary. Fly to Amsterdam during the next big seed-fest and invest in whatever wins the grand jury prize for cold weather hybrids that grow next to freeway overpasses. Plant liberally around the greater Detroit metro area, harvest what doesn't get found first by LE or a lawn mower, (budget crisis= no more mowing MI.), and get a ROI that makes Halliburton look like a social service agency. If there is one thing that MI. is going to need in the coming years, it's drugs. And weed is the opiate of the masses.
The plan needs more flushing out, but this is just off the top of my head. Think outside the box; that's the name of the game in tough times.
Best of luck, don't leave any change on the table.
