Grape-picking in the Douro

I’m going by train to the grape-picking festivities.

Let’s go by train to the grape-picking in the Douro. 
It’s a great programme. A party. I am going by train to the Grape-picking festivities. 
Why not come with me next September? 

As soon as I have any news, I’ll let you know. 
But take a note in your diary anyway. See you soon!
