I don' t think this alliance is for El Batey of Sosua, Chris...No one seems really sure what this organization is...
A batey, in my understanding, is a barrio or community...
Edited to add: But I think it would be a fine idea to give to the jar at the Britannia pub - I was just reading about the the cause and I think Harry, the guy in charge, is a lovely, lovely person. What a great idea and what a nice way to do something for the community.
