Freedom of speech? Not for you, Randy! Unless you speak Spanish or some other non-English language. Funny how that works.
According to the 2000 US Census 7.7 times as many people claim English as their primary language versus Spanish. Spanish is #2 in this great country though. And ahead of English and Spanish is the almighty dollar/peso/euro/etc. Hmmmm.
Sign Language is #15 (more than Japanese). Therefore, I think we may see MLB catering to these 1/2 million people. The sign for "red" is made by making a movement that looks like you are stroking your lips (one time) with the tip of your index finger. I hope to see this on a jersey... with moving finger! If we can use computers to call balls-and-strikes, then this technology has to be there.
