As we understand it, the COHI group was formed to purchase property and avoid issues with the Brooklyn Heights people. Some would have refused to sell to the Dubs. Likely there were other reasons not known to us personally.
One of the princpals in COHI was Dallas (Dick) F. Wallace, a very wealthy Dub. He was the founder of Tech Tire Patch which in turn gave way to the Mighty Distributing franchise empire. Dick died several years ago, he had MS I believe.
