From Dave Thomas: The World Freestyle (Frisbee) Championships are being held at UCSC Upper East Fields Saturday and Sunday. Here's a link to their website for more info including a video clip:www.santacruzfreestyle.com. But on FRIDAY night, the independent film "The Invisible String" will be shown outdoors on the same field. It's a documentary featuring archived footage and commentary on the magic of throwing a frisbee. A history of the spirit of the thing if you will. Here's a link to the trailer: http://theinvisiblestring.wordpress.com/The Invisible Stringtheinvisiblestring.wordpress.comThe film will show at 8:30 - probably our only chance to see it until it comes out on DVD.
