Road Train

On the 28th day we were driving from Alice Springs to Karlu Karlu and on the way we saw a road train 🚂 and he let us pass him. While we were passing him my dad said on the radio to the truck driver "can you please toot the horn for us?". He said sure mate and then tooted to us. His truck was Wriggling so much because the truck was 50 meters long!!!!!!!!!!!!!!!!!
