Let's do the you and two friends idea, and I'm happy to have anyone 1st through 5th grade. We will tidepool either at Pigeon Point Light House (just south of Pescadero) or Fitzgerald Marine Reserve (just north of Half Moon Bay), and we'll meet up either in Half Moon Bay or Pescadero, whichever is more convenient for the family. Lunch options are: I provide a picnic lunch for the kids and we eat there on the coast, or we go out to eat in Pescadero or Half Moon Bay, depending on where we end up tide pooling.
