Those are very nice sunset photos at Dorney Park! One thing I noticed while I was there during my first visit back in June was that after 8:30 pm it went dark quite fast! I am not really use to that because it's quite flat where I live!
But, out of my two days being there, I had only seen the sunset the first night because the second night was overcast and raining! But, Dorney Park was a beautiful park during the day and at night!
