     The day was unforgettable. We met each other in the park and we took some photos. After that, we started answering the questions. The first location the app gave us was the location near NLB Bank in the Shopping Center.

We answered the question and we got thirty points. It was really good motivation.

We continued to the next location the app gave us. It was in the Shopping Center, again. Less than ten minutes we answered the question. An interesting feeling was our best friend, those moments.
