Aha! That's where they got the idea. I have a $2 bill in my wallet because it is fun to mess with storekeeper's heads occasionally (along with Sacajowea dollars, which no one else will use, either... and they are also attractive). I also use both $2 bills and 2 Lempira notes from Honduras (pretty purple bill with the legendary founder of the country on it) for bookmarks. 73 Jan
