When I lived near DC as a kid, I loved when they had the kite festival on the Mall. There were so many different kinds of kites, and I always wanted to be one of the people who got mine super high in the sky. And of course, we had to check out the selection at the Air and Space Museum.
It seems the Bay Area has their own kite festival, being held this weekend in Berkeley. Held at Cesar Chavez Park at the Berkeley Marina, it looks like there will be plenty to see, up in the air and on the ground. Being Berkeley, they have incorporated the kite traditions of many cultures from Japan to New Zealand. There will be lessons on flying acrobatic kites and shows of team kite flying. Their slideshow shows kites as big as the balloons at the Macy's Thanksgiving Parade - but no helium needed here! Just some good wind.
All in all, sounds like a feast for the eyes. Aim high!
