Ryder Robinson (his dad is rocker Chris Robinson) is a man about town. His mom Kate Hudson was elsewhere so family friend/actress Sara Foster thought she would show the kid a good time.  He is freaking beside himself with excitement.  I'm guessing Ryder is too young to appreciate the hotness of the situation.  Who is this Sara Foster and where do I sign-up?

The free rides don't stop there! Ryder also hit up Grandparents Goldie Hawn and Kurt Russell for some quality traveling time. Goldie mostly, Kurt was smart and made the boy walk.  That hair is heavy.
