Come explore the tidepools of Fitzgerald Marine Reserve (low tide should be around 10:44 today), and, after the tide comes back in, have a picnic, lounge around, wander through Half Moon Bay, and generally expend a day in an unproductive manner. Plan on getting back around 5:00pm, unless your carpool opts to have dinner out at the coast. Bring a picnic lunch, plenty of water and sunscreen, layers in case it gets cool, nonslip footwear that will survive getting wet, money for carpool and optional dinner, and maybe a camera or some beach toys. Meet at carpool point #7.
Directions to LPSS carpool point #7 (Edgewood / 280 Park 'N Ride): Exit 280 onto Edgewood Road east in Redwood City. The lot is next to the freeway.
