In the interest of accuracy, I should expand up on my reference to the "gun runner" who was the founder of the Museum. Lonely Planet's travel guide says,"Perhaps as interesting as the museum is the story of its founder, Carlos Cardoen, who allegedly sold armaments to Iraq during the time of Saddam Hussein's reign, and was instrumental in bringing tourism to the Colchagua Valley by supporting the creation of museums and other wine-centric attractions." It also says that, other than visiting this museum, "there's not much else to be seen and done here." This seems borne out by my afternoon stroll.
I did find that I was not terribly hungry this evening, but I chanced to run into Carol, and the two of us stopped for a simple sandwich at a small cafe near the hotel.
And so ends the day.
