Reference for Sukkah 75:7

דיקא נמי מדקתני מי שבא בדרך ואין בידו לולב דאי ס"ד ביו"ט ראשון מי שרי:

And this can also be learned from a precise reading of the mishnah which teaches: One who was on a journey and had no lulav to take. If you thought this referred to the first day of the Festival, is it permitted [to travel on that day]?
