Look! Look up ahead! Do you see the giant rainbow painted around the tunnel? This is the Rainbow Tunnel! People painted that rainbow way back in 1970, and ever since, it has said welcome home to everyone driving back into Marin.
Now the tunnel has a new name too. It's called the Robin Williams Tunnel. Robin Williams was a super funny actor who lived here in Marin. Do you know the big blue Genie in Aladdin, who grants three wishes? That was his voice!
So here's a tunnel game. When we're inside, everybody make a secret wish, just like Aladdin. Don't say it out loud, or it might not come true!
