Well, it seems that you and I are the only ongoing Gringo enthusiasts still reading forums. I guess you are 'Bill' on CSW and 'William' on BGG. We begin Monterey July 23rd - I'll be playing the Mexicans. If it goes well at all, I'll write how it goes either here or CSW.
I read them, I just don't have an answer for you as I haven't played that one.
