I'd like to travel everywhere. But if I only had one choice,

I'd go for the 1960s or early 1970s. As I expressed somewhere, that was the time the 80% of my favourite music was created.

so basically the same time that you wrote Wing'd Icarus.
I'd like to talk with a young Hitler and eventually kill him before his team starts the WW2. But changing the past is unpredictable and may be extremely insidious as we, the Back To The Future movies fans, learned.
