One of my most favorite experiences in New York City was watching the Christmas Spectacular at Radio City Music Hall.
The word "spectacular" cannot even express the experience of feeling Christmas so deep within you, that your heart just wants to burst. The feeling of elation from the beautiful music, the lights, the atmosphere, and the beautiful auditorium caused my eyes to leak with tears of shear joy.
Then there was Santa Claus. When Santa's sleigh came out, I could almost feel the touch of the snow tingling on my face. If you haven't been to New York at Christmas, you are missing it. If I could, I would go every year.
