Pictures for my grandson, Ethan

This is a garbage truck we saw during our trip to Savannah. It went along the street right next to our hotel when we were out walking one morning. 
This is a real old car we saw in a museum in Savannah. I don't think I'd like to ride in this car in the rain. Would you? 
This old garbage truck was the type used in San Franciso about 75 years ago. The picture is from an article on the history of trucks that we have for Ethan. 
Can you guess what kind of a truck this is? It is a truck for washing the inside of tunnels. The men who drive this truck drive it all over California to wash the tunnels. There are only two trucks like this in the whole State.
