I Like this one.
Kauai Humane Society http://kauaihumane.org
Hawaii does not have much exposure to the crypto currencies, and this would be a great way of introducing them. Plus, there is a huge amount of international tourist traffic that passes by this particular location, as it is off one of the few main roads in Kauai. This will help spread the word far and wide, hopefully! If we can get one small humane society to agree to accept Quark and see how valuable it can be for them, we may then be able to get many more humane societies to accept, throughout the U.S... Thank you for considering them.
