Sorry to disagree, Willy, but I believe the registered corporate office was on Kolb Road in the far south of Tuscon.  

BTW, I recently looked up industrial "for lease" listings in the South Tuscon area and did not find this property.  That in itself does not mean it was never on the market.  I could have missed it, or it was never listed (leased privately), or it has not been listed as yet, or the company just wanted a more prestigious-looking address while they continue to occupy the warehouse.  That latter option I deem doubtful.  Time will tell.

...not worth a phone call, in my opinion.
