Hovercraft at Ocean Beach
Brought the hovercraft out to Ocean Beach. More than 30 people went for a ride. Kids, teens, thirtysomethings, and some senior citizens went for a ride. A good time on a gorgeous day. -

Sidewalk Science is where we bring some science equipment to a sidewalk near you. Hopefully, you'll have fun and learn some science too. Thanks to Sandy Olkowski, photographer.
