Bay seniors don’t like to boast about our influence on modern culture but we all know it’s been massive. 50 years ago when we were tossing frisbees to our friends and golden retrievers who knew one day that it would be a professional sport? There are 5 million players now in the US. To see how much things have changed you might want to spend a few hours Monday afternoon May 26 at McInnis Park in San Rafael. It’s the 15th annual Ultimate Frisbee Tournament and it’s considerably more organized than you may remember though there are no referees and the players call their own fouls. It appears to be free. “Frisbee”, FYI was named after a 1948 Connecticut pie company whose plates, local students discovered, could be thrown and caught.
