Animal Planet has put a brief clip from Raising Sancho on its website called "Fishing Lessons."
I hope a full DVD is coming.
Update: Some of you have noted that you can't view the clip. Try this: when you click on the link, look to the right for the categories. Check for "Mutual of Omaha's Wild Kingdom" and then click "view galleries." From there you should be able to select the clip.
Another update: Reader and Sancho fan TP from the United Kingdom sends this site along. Lots of stills from Raising Sancho.
Though Carolina mentioned that the show was aired in Central and South America recently, I did not get as many visitors from that airing as I did from the European and U.S. showings. This does not surprise me. I received very few visitors from the Asian showings as well (with the exception of visitor chittraporn from Thailand). It must be a language issue. Later on, when I have more time, I'm going to search the Spanish and Portuguese Googles and see if anyone is writing on Sancho in those languages. Also, if any of you find anything, please let me know.
