white Nights

There are the White Nights in Saint Petersburg! Have you seen the White Nights?

I have only been to Saint Petersburg in March. I loved my trip but it was very cold! I should return in June so I can see the white nights. (In English, you would probably not capitalize "white nights.")

White Nights

There are "White Nights" in Sant-Peterburg now! Have you ever seen the "White Nights"?

Нет, но я очень хочу. ))
