SPAIN - 2009: industrial tanks for sale. One would think that big industrial facilities are sold through brokers, agents, and so on. Instead, here there's a phone number. Whoever owns this rusted, derelict tanks, looks desperate enough to trust that someone driving on the highway will see the sign, pick up the phone and say "Hi, I was just thinking of buying a dozen half destroyed tanks to store a zillion liters of whatever". Even big industry in the south is something to deal with face to face, possibly having a drink.
