Whenever I travel, I try and make it a point to shoot at least one sunrise. This is especially true in a big, popular city, because all the beautiful and famous spots are overrun with tourists during sunset. So it can make for an interesting photo to capture a place when it is empty (or nearly so). When I was in Prague I got up at 4:30am and headed out so that I could capture the Charles Bridge without all the crowds. Success! There were only a few people there and it was pretty amazing to have this gorgeous spot all to myself!
