At the drop of a hat

I took this photo from the outside of Park Güel in Barcelona, Spain. This is one of the Antoni Gaudí's great works, and also a part of UNESCO World Heritage Site. That morning, I visited the Sagrada Família for the first time. First of all, I needed to get in line for 40 minutes to buy an entrance ticket. Then, I went inside of the Sagrada Família. After spending a long time at the Sagrada Família, I headed toward Park Güel on foot. It wasn't really close, but it was fun to walk in Barcelona. When I was able to see a part of Park Güel, I started to take pictures at the drop of a hat.
