Here's a good map of SOWA from Williams & Dame, that Mark had posted some time ago. A little outdated, as "3720" and "Alexan" are named, but it's an excellent way to zoom right into where you would put Vestas Americas HQ, if you were calling the shots!
There are superblocks just north and south of 33, but right across from the park would have to be a prime location, suitable for their goal, I would think.
